I'm attempting to do something not a lot of people have done in one of these trucks, I plan to drive the pan-american highway. I'll start in Prudhoe bay Alaska and end in Argentina, although I'll probably see how far I can make it south in Chile, I'm not following the highway, I'm gonna float around where ever I feel and in south America and Mexico I'll probably zig zag from coast to coast. I have a 76 chevy k20, it currently has a 350/th400 with a 10 bolt front end, 14 bolt rear and an np208 transfer case. I plan to swap it for a lightly modified 24v common rail cummins, I'll keep the axles, and find a manual transmission and transfer case (probably an np205) to fit the cummins, I'm only choosing the cummins for reliability, I need it to be capable of running high sulfer fuel and I'm going to "bulletproof" it. I'm going to take the bed off and build a camper on the back, I'm looking at 35in tires and a 4in lift. For those who are unfamiliar, some of the roads in south America are straight up offroad trails and I need the vehicle to be capable but also dependable, I'll probably be gone for 1.5-2 years. I'm looking for any advice people have to get the truck to a point I don't have to worry about it, what suspension can I get that will flex some but still be able to handle the weight of the camper? Any advice is appreciated. Thanks!
