I built it to take a pounding for 25 years. Part of being raised on a farm i guess. All .134 x 13/4 on 2x3x.125 rails. I weigh 275 in my flight suit. It is a typical stripped body with glass decklid and hood, all windows lexan. I have a 3 qt accumulater, an alternater, a primerplus system , dana 60 and megablock that weighs a bunch. Aluminum interior, and a fuel cell that will get you four miles down the road if you lean it out
