I keep 2 8 foot 2x4s in the back of my truck at all times for hauling sheet materials. Having hard skids in place makes loading and unloading easier and ensures stuff like drywall and doorskin doesn't get taco'd up. This is a deeply stupid problem to have and I often wish I had a 70's era Ranger or F100 with a new-ish power train shoehorned in.
