My mind wanders its own random paths, but my wife needed emergency surgery yesterday, so I have been with her as much as possible, and I have never been able to focus on important things if another important thing needs to be done first.
Grad school finals, finding a new house, cleaning and clearing out Mom's house so I can sell it, etc.
We just got a contract on a house near my wife's work yesterday and I passed my first year, but I can't focus on anything important besides my wife getting better.
She will be fine, but while she is in the hospital, I can't focus on moving, Mom's house, etc.
Since I have almost exclusively needed to pack Mom's horde by myself and I was always unreasonably optimistic about what I could pack and load in a weekend, I have spent enough on rentals to buy an old truck, van, box truck, etc., and when I mentioned this to my wife, she asked if we could convert it into a camper afterward.
YouTube keeps recommending people building campers, camping trailers, etc, and I love watching people build things.
I just skimmed the 240 posts here (Class a motorhomes aerodynamics) and happened to find more salient information from this gentleman who doesn't capitalize his name:
than this one.
I want to deep-dive into the different types of trailers and the pros and cons of each when I have the chance (and a mouse), but let me just share some things that stood out:

I don't know that we need to worry about downforce or lift with trailers, but if I were to build one, I would want to make one like this, which took too long just to stitch together:
I have seen people make "Teardrop" trailers, but we established 10-15 years ago that most people don't have any idea what is aerodynamic (hence freebeard's quote), but let's say that I take two 2" foam boards, cut them to that shape, screw dozens of 2x2s between them, and fold layers of thin foamboard, glued together, around them until I have a 2" thick aerodynamic foam shape--as long as I only think in two dimensions.
Would focusing on the sides with a flat top and bottom be more effective?
This would undoubtedly be better and easier to fabricate than anything else:
YouTube randomly suggested the second video and I keep meaning to see if we dissected it, but while it looked much better than the first one, he received much worse results:

Side gust sensitivity would be an unknown quantity, so you'd want to start out with conservative driving speeds until your confidence builds up.
Modern accelerometer sensor technology, software, and actuators would be capable of deploying aerodynamic countermeasures nearly instantly, to compensate for yaw-moments; however, that's beyond my expertise.
I have read many pros and cons of different types of trailers, campers, etc., and the thing is, it always depends.
"This is better than that"--it depends!
There is a post on Imgur asking why pop-up trailers exist and Internet strangers were not kind, but this one of indeterminate weight is going for $25,000: Ranger 12 Sofa Bed For Sale
Do you have any idea what kind of tent you can buy for $25,000?!
That is 20' W x 32.5' L x 10' H at peak and can be erected in less than 30 minutes with the help of 4 adults, so definitely more difficult than a pop-up camper, but this has more square footage than a pickup and pop-up trailer would need!
I like different ideas, but most of the time, I think that a good tent and camping gear, which would fit in my trunk, are better than a camping trailer.
I really like bathrooms, though, and if it happens to be cold, I would vastly prefer somewhere insulated to go to the bathroom, change, shower, etc.
I had been wondering about pop-outception, but since I keep thinking that a tent makes more sense than trailers for many situations, I just want an insulated bathroom, I wondered about nested fiberglass and foam boxes that you separate, latch together the other way, and install a solar shower on top.
Or you could just have a 7' foam and fiberglass cargo trailer with a camping toilet.
You remove the toilet, tent, sleeping bags, and everything else that goes in the tent, set up the tent, but the pads, bags, and everything else in the tent, flip the trailer, put the toilet back in, and remove it to change clothes, shower, etc.
Hmm...
He specified corrugated metal, but how about fiberglass and foamboard?
Okay, but for smaller trailers, isn't it more efficient to have a cargo box than a trailer?
Unless you mount this to a truck of van, it would be wider than the vehicle, and I don't think that an aerodynamic base would make a very good base at all.
Can you make sense of my even-more-distracted ramblings?!
I will try to edit this later, I just wanted to put this together, but I was supposed to leave to help Mom and my brother an hour ago.
How did it take an hour to put together this mess?!
My browser is being slow...

Plywood still needs a fiberglass coating. Polymetal is prefinished. Stitch-and-glue Polymetal may be feasible.
Thanks for considering those trailer designs. They could be combined. The tilter was originally an ice fishing hut design. It could be a single seater/shower; the proportion would be taller instead of wider.

....on the tow vehicle. Start there. For sake of completeness:
Triangular wings fold out to make an hexagon platform. It would be twice the vehicle width or 15ft.

Do you see how the top bows collapse together and fold, and a third of the platform swings up and over with the hatch? The sides could be bug screens.

I think that if I had technology sufficiently advanced to be indistinguishable from magic, I would have plans and schemes other than camping, but honestly, giving myself a 4-day work week every week so I could camp regularly would be pretty sweet.
If the teardrop trailer were 8' tall, the total length being 21'1".
That doesn't sound terrible, but how on Earth would you fabricate it?
Maybe if you are an eccentric millionaire.
I focus on foam because 2" of it is r13.
Again, when comparing trailers, everything depends, so how do you compare them?
What you can get for $25,000 seems bizarre, but I can't think of a better comparison.
I don't know how long that A-frame pop-up is, but the entire roof and sides are rigid.
I kept reading that they were stronger than tents, which didn't make sense, and you could get a vastly larger Army surplus tent, which I am sure would be stronger, but maybe the A-frame popup would be tougher.
It claims the retail price is $35,163, but you won't pay that, no Sir, not you!
You won't even pay $24,975!
Oh boy! You can have it for the low low price of [enters temp e-mail address and fake contact information] $23,975!
This looks like it is supposed to pop up, but you just have the back end pop up so you can enter it normally and stand in the very back?
It has its own porch with railing?
I can't imagine buying the A-frame, but it actually makes sense to me.
I don't want to constantly explain that it doesn't do anything, it is for kids, while the adults camp on the porch.
By the way, it had one of those popups pop up when I was trying to look at a popup claiming that you could get $500 off any vehicle, but I couldn't figure out how to type or paste into any of the fields.
Autofill worked, not that I wanted to give any real information!
Comments from that Imgur post:
"It's better than a tent and cheaper than rent."
"It's not intended to be lived in."
"1. get to sleep on a mattress 2. Many have a small kitchen, i.e., sink and maybe a 3 burner stove. 2. Places to sit."
1. 2. 2.
Hmmm...
Are those mattresses any better than this?
There should be adequate room for a couple rolled-up mattresses, a tent, sleeping bags, a 3-burner stove, inside your brand-new genuine patented freebeard toilet coffin!™
I am positive the padded benches in the $25,000 popup are more comfortable than the $59 picnic bench, but $25,000 vs $59!
Would you rather be in an Army surplus tent or a popup in a thunderstorm?
"It’s a cabin tent that you can tow with a sedan. Lighten up, Francis."
Not helpful.
The special Internet price for the cheapest one on that site $6,475, it is 18' long, and weighs 1,601 pounds, while my Camry is only rated for 1,600.
"So you can tow them with something that doesn't cost $85k."
They compare it to a 5th wheel?!
"It's solid so it's far more capable of withstanding thunderstorms & winds, you can haul your usual carload of stuff PLUS anything else you want to have with you like your kids bikes, etc., & they're effn huge inside compared to a tent. I dunno about A/C but okay I guess, you pay extra for the fuel you use. We had a real simple one when I was a kid, no power just a 3'x3'x6' icebox, & just having it up off the ground when a big storm rolls in & drenches everything in 4" of rainfall is pretty huge."
The A frame is more solid than an Army surplus tent, but the last one is only solid when folded.
The material just looks like a tent, which wouldn't hold up.
You can buy an Army surplus tent for about the cost of that popup, so they are comparing a tent that costs a fraction as much as the popup, which is ridiculous.
"For 8 years my dad towed one to 48 states, two worlds fairs and 4 provinces. They allowed a working class family to see the world."
He couldn't have done that with a wagon and a tent?
"Off the ground is warmer & safer & more comfortable. Can haul way more since it's a trailer, like loads of food and maybe firewood and stuff. Stronger than a tent."
If you have a pickup, you can build a platform and put it down wherever to be off the ground.
"[P]op-ups aren’t intended for off-grid camping, they’re intended for campgrounds where power/water are readily available." "Popups remove the worst aspects of tent camping while not making you feel like you’re in a traveling hotel the way big trailers and RV’s do. [...A] pop is the happy medium for me for comfortable family camping at established parks and campgrounds without spending $200k on a second home with wheels."
How much camping would you need to do to pay for the cost of a trailer and gas?

Might I suggest a Burro, Casita, or Scamp? All about 11 to 17 ft long, burros being about 1100lbs and Casitas being 2000 ish. My casita improves my trucks mileage by a couple of mpg on the long hitch. IIRC, you're tallish, so all of these require to scrunch up a bit in the sleeping configuration unless you mod it for the tall person.
You can score a burro or scamp for a couple hundred, sometimes
The pointy roof popups don't have much headroom except in the center, they really need a gable over the bed, have seen them with a gable over the toilet, which I think is mandatory
Neighbor across the street aquired a hard sided popup since he likes camping(?) In bear country and the rangers won't allow tents.

Selling as a project. It’s a no crank no start so you’ll likely need to take it home with a trailer or tow.

Could I get this running faster than one of my current Civic coupes?!
In theory, I could gut it, and convert it into a trailer I could tow with a sedan, but that seems like a waste.
Hopefully, it enjoys a better fate.

I am the second owner. The car was driven mostly in Wyoming. I drove this car from Wyoming to Phoenix on March, 2024. This is nice car for someone interested in a project car. it's 6 speed manual and runs pretty fast. The spark plug in Cylinder 1 blew off. Therefore, we had to rethread the spark plug hole and install new spark plug and an O2 sensor. The A/C stopped working and I don't have time to fix what's wrong right now. I bought a new car because my wife can't drive manual shift. Therefore, I am selling this because I don't want to keep paying insurance and a parking spot. This runs well. But if you don't have any sense in mechanical know how this is not the car for you. Genuine inquiries only. message me for more information. The car is in fair condition and it is reflected in the price.

I swear that I was getting off of the computer to go and be productive! Really!
I was closing tabs when I saw "Don’t Fall For Aerodynamic Junk Science When Shopping For Trailers (Especially For Your EV)" by Jennifer Sensiba.
I thought it was a pretty good read, as much as I could understand it in the hospital with my wife, not having slept well the night before, but this is Google's summary:
Quote:
This article argues that fuel efficiency is a major consideration when choosing a travel trailer, especially for electric vehicles (EVs). Many trailers marketed as aerodynamic are misleading and prioritize aesthetics over actual efficiency.
Here are key points:
Aerodynamics are more important than weight: While a lighter trailer is better, focusing solely on weight is less critical than good aerodynamic design.
Trailer weight doesn't significantly impact fuel consumption unless the trailer is very heavy or the route involves steep inclines.
Teardrop trailers exemplify good and bad design: The classic teardrop shape with a blunt front, curved body, and tapered tail minimizes drag. However, some "teardrop" trailers sacrifice this teardrop shape for more living space, hurting fuel efficiency.
Trailer maintenance is crucial: Proper tire inflation, bearing lubrication, and other maintenance ensure optimal efficiency regardless of the trailer design.
The article advises against falling for gimmicks and emphasizes understanding aerodynamics to choose a truly efficient trailer that saves fuel and reduces your environmental impact.
This article dives deeper into optimizing the aerodynamics of larger trailers for electric vehicles (EVs) and avoiding misleading "faux-aero" designs.
Key points:
Balance size and shape: A teardrop shape is most aerodynamic, but size also matters. A larger teardrop will have more drag than a smaller one. The goal is to find a balance between efficiency and usable space.
Kammback design for trailers: Similar to cars, a Kammback design with an abrupt tail truncation helps minimize the drag-inducing vacuum zone behind the trailer.
Minimizing frontal area: Smaller trailers have less drag, but this reduces usable space. Pop-up campers offer a compromise with a smaller folded size that expands for use.
Gimmicks to avoid:
Rounded brick shapes: Don't be fooled by rounded corners on boxy trailers. They offer minimal aerodynamic benefit.
Fake teardrop designs: Trailers vaguely resembling teardrops but lacking proper engineering for airflow create drag.
Bullet-shaped designs: These prioritize aesthetics over function, neglecting the crucial rear vacuum zone.
Overly large pop-up campers: While smaller than a full-sized trailer when folded, excessively large pop-ups can be heavy and negate their efficiency advantage.
The article emphasizes informing consumers to combat these misleading designs and avoid hindering the reputation of electric tow vehicles.
The article suggests pop-up campers can be further improved for aerodynamics, and mentions consulting Ecomodder for DIY modifications if you're handy with tools.
