The truck must have a flatbed and a payload capacity of 1800 lb or more depending on how you pack. The demo model weighs 1750 lb fully loaded. The base of the camper is approximately 83" (L) x 75" (W). In order for the included ladder to be lowered, the camper must extend over the back of the bed by about 3", but the tie downs at the rear corners will have to angle forward or the bed anchor points extended to the rear. Consult a metal fabricator to see if the bed can be lengthened. The demonstration truck currently being constructed has a 82 7/8" (L) x 76" (W) flatbed. Ideal dimensions are 80"(L)x77"(W). Trucks come in multiple configurations with a range of carrying capacities. The Ford Ranger is best in class at 1860 lb. It also depends on how heavy the flatbed is: remember that the stock bed is removed, but the flatbed can weigh less, the same or more than the stock bed depending on construction. For those trucks with payload capacity less than 1800 lb, overloads or upgraded springs will be necessary. If going on washboard roads, shock upgrades are recommended.
