I built an expendition "tear drop" last summer. It was nice. I had a custom frame built (most tear drops use Harbor freight cheesy frames). I used Pro-Comp suspension with spring over lift and used the same hubs as my Blazer, so the wheel pattern was the exact same and Im using the same GM rally wheels that are on my truck.
The camper was fully insulated, roof and flooring and was pretty awesome actually. I was heartbroken when I had to take it apart.
If you can see the entire album, youll see the build pics from beginning to end and youll see how bad the mold had gotten in a short period of time.
ANyways. the "box" was 4' x 8' and it was built alot like a tear drop with the "kitchen" in the back. And you had the sleeping are which was 4' wide and over 6' long. The back area had a 10gal water tank with pump and faucet. I had special deep cycle batteries all wired up. It had LED lighting, complete with dome lights, porch lights and it had DVD player. Electric push/pull fan. I used Tear drop doors and got some RV windows from junkyard. The interior looked like a mini cabin.
Anyways. I had other plans for it, but mother nature took hold and ruined my camper. You see, we built this thing outside under a cover but it rained all summer long and was high humidity. Long story short, MOLD got into the wood and ruined the camper. I took it apart, sold the parts and kept the trailer and just put some pressure treated wood down to haul ATVs.
My buddy that helped me is building one right now using an older Aluminum cargo trailer and he basically chopped it down and made it just big enough to put his ATV in it.
Anyways. I had a pretty good build thread going on another forums but not sure if the pics are still there.
I have over 160 pics of my build but here are a few;
This was once I got it built and out testing it off roading. Im using a TREG style hitch setup, it allows full rotation and up and down and side to side movement. No slop and no noise.
Galley area at nite , complete with faucet and stainless steel sink and LED
Interior shot , with twin size tri-fold matteress
Other end of interior, complete with cubby hole for gear and entertainment center.
Procomp shocks, 3500lb axles, 2000lb springs
Mold got in everywhere and it was unsafe to keep/sleep in. so I took it apart and took all the stuff out and hit it with a chainsaw.
Here is how I use it now. lol.
