I'm going to be starting a project truck in the up coming year or two and was looking for some tips from people who have done custom builds before. It's not exactly a jeep but it's an old AMC drive line combined with a wagon and I figured it be the place to a ask about custom vehicles. I've work on plenty of trucks cars and jeeps doing body and mechanical work. I swapped Subframes, pulled motors, and built patch panels but never custom built a truck before. I need a vehicle with fuel mileage in the teens, low end torque and that can fit a popup camper setup in the back. My plan is to take a Chevy 3/4 ton suburban and put a 4.2L inline six with a torqueflight 727 tranny and put it in place of the v8 and 700r4 because of personal preference. I like the body and hate the driveline and a wagoner is to small. I don't know what kind of axles to use but I have Egan 3/4 axle laying around and don't know what would work best with the rest of the driveline. I don't know what transfer case the old wagoners use but I liked the quadratrack setup. As far as the body goes I need to raise the whole roof, add two inches of lift, redesign the whole rear end, and make the doors detachable. The back windows and sides are going to fold out into beds, the top pop up for hight, the rear baker doors will be the entrance way, and add in a fold down propane grill top off one of the back doors. The outside is just going to have a wrap up shower curtain in a hide away compartment with shower set and have a 5-10 gallon top tank. Also I want to convert it to manual steering. It's basically going to be a road trip/base camp truck for when I go camping out in the boonies. Any tip would help I'm just starting to get into custom builds and this is the first I'll be building once I get everything ready and planed.
