So I have been working on the stock structure of this now that the weather is good. I got all of the rotten wood rebuilt and most of the siding back on and the factory lift cables attached and lifting properly. I got a new propane setup on the front, fixed a leaking toilet fill valve, and checked out all the appliances and found them working well. The fridge will freeze inside at anything over 1/2 way up the temp dial. I am replacing all the lights inside with LEDs and will probably add a fan/vent to one of the existing vents.
Now I'm thinking about that boat tail and some work on the front and maybe skinning the bottom. The bottom skin is a little tricky as the lift cables are exposed under there along with stuff like the holding tanks and dump plumbing.
I want to add some racks on the rear bumper for waterproof bins and maybe a firewood rack, and move the spare somewhere else. The bumper already sticks out but I would add another 8" or so. That would allow me to put a 18-24" or so boattail on the back. I thought I could attach it to the upper clamshell and just let it go down and cover and overlap my bumper box. Just have it taper slightly from the top and pinch in from the sides. Put new taillights on the end.
For the front it sits lower then the truck, maybe add a 12" extension off the roof of the SUV, but it does stick out more on the sides, especially the upper part where the upper sides of the SUV start to to pull inward.
I was looking at metal duct work and wondered if a 4" round duct opened up on it's seam and placed as a 1/2 round piece vertically on each edge of the front would work. then make some kind of cap for it blended to the top curve.
I also want to add a nose cone and boattail to the awning tube and tapers for behind the roof vents, remove the TV antenna all together, and make a aero cover for the plumbing vent.
