Yeah, my build will mainly focus on heater and general climate control, solar, fridge, and other such electronics toys along with a comfy space to sit and sleep . I'll probably fit at least 265's but maybe a touch bigger but nothing radical. I've built a few rigs for more serious offroad but this rig will be mainly to haul my toys and be my base camp. 4x4'n is fun but fully throttle on an angry 2-stroke (sled or moto) or even pinned on an MTB is more my speed when it comes to off pavement fun. My 4x4 capability will be mainly for snow and sandy desert roads, nothing too extreme.
Interestingly, having recently helped a friend install an Espar, it's pretty cool how easy it is to run wires, tap extra fuel lines, and generally install add-ons. Just don't mess with the ECU.
