ennored — Nice example, and I like the trailer tail light in the lower left.

Hadn't noticed that.

It's a random image from the web, but I recognize the intersection, Catalpa and Woodward, so I know the picture is from the Woodward cruise. 1 or 2 of everything out that weekend. Old truck with explosion proof housings used for taillights, check.

This just turned into a, “ready to run in ten years” kind of project.

The fuel “savings” aren’t going to justify a pretty much solo-use, next-to-empty vehicle the majority of its miles.

It’s NOT the right vehicle.

If I believed it was and I just HAD to get an annual tetanus shot from hereon, I’d work on the rear exit (hitch mounted case with removable aero overhang as shown elsewhere) AND

I would focus on building an aero trailer that relied on the work done by Aerohead & Aerostealth re 100-mph tractor-trailers & buses.

Aerodynamics aren’t really going to matter much around town. It’s the steady-state Highway problem where it comes into its own. Dramatic drop in horsepower demand given close coupling.

That close-coupling is worthy of the effort, IMO.

Could you provide examples?

I understand your point, but for a lot of us here this is a hobby/for fun. Speaking for myself, driving 1500 miles to compete in a fuel economy competition doesn't make any sense at all, but I still do it once a year because I enjoy the challenge. Modifying my car to improve its highway fuel consumption doesn't make sense when I could realize far more savings by leaving it at home and taking the train to the East Coast later this month, but I enjoy the car more and am comfortable with that emotional decision. I suspect the same is true of aardvarcus.

Shaneajanderson,
Thank you for the suggestion, I am not sure that I would want to use a bedcover as part of my cargo area conversion. I do have a hard tri-folding cover on my heavy hauling/towing truck, they are great!

Ennored,
Thank you for the suggestions. I think the Magnum RT is the closest to working I have seen thus far, but isn’t quite what I was imagining. I am starting to think that exactly what I am looking for doesn’t exist. (Bigger version of a 2000's celica hatchback.)

2000mc,
The Aztec isn’t a bad suggestion, the two part with the upper being mostly glass would be nice if I converted the suburban to a step side tailgate.

Slowmover,
Thanks, I appreciate your feedback. I realize I have not posted a complete explanation as to why I chose to do what I am doing to the vehicle in question (largely because I don’t think anyone would read it nor would I expect others to draw my same conclusions) so I am not surprised the starting off point for this build to be questioned. I realize using it for what I have suggested is rather obscure. However the vehicle has been and will continue to be used up to its capabilities on a fairly regular basis. Things change and I don’t know that I would start this exact project over again if I had it to do over again, however it is what it is at this point and I intend to press forward with completing this project which I have started.
I would rather not need to rely on a trailer for the drag coefficient I wish to achieve, as I also plan to tow with this vehicle. It is also much more handy and maneuverable without a trailer.

Vman455,
Yes, a big part of this is for hobby/fun. I enjoy the challenge of doing something others are not doing.

I was curious what slowmover was referring to. But if you're missing some of the things, these are the ones I have in https://ecomodder.com/forum/member-f...technical.html

ones I have

Thanks!
The one probably most germane would the Greyhound Bus,which was chopped by four-feet,pulling a gap-filled,full-boat-tailed cargo trailer.

What I'm proposing would be like this.
