So I called Budget, and their rates matched my original quotes with discounts. The online reservation checker is junk, and won't show you any discounts.
So new problem: I was planning on using a 4x8 sheet of 1-inch thick Rmax insulation foam as a door plug for my Rental Truck. Pull the truck door down a few feet, and wedge the Rmax plug into place. Then, cut a door out of that plug for quiet, easy in-and-outs.
The problem: This Rmax foam crumbles and becomes moop easy. I definitely have to Gaff-tape the heck out of any exposed foam. I'm more worried about cutting it, and installing hinges on it to make a door. Can I even bolt a hinge and expect this stuff to hold it? I don't think so. It's pretty Fragile.
So Dilemma- make an 2x4 actual hinged wooden door with frame around the Rmax or find some way to make a Duct dape or low impact doorway out of the Rmax that won't degrade into rubble.
I suck at carpentry and will basically have to hand-saw 2x4's, so I'd love to avoid the crazy frame.
Suggestions graciously accepted... I'm about to hit the road but I will make one stop at civilization before touching down on playa.
Heres the Idea for the back plug:

and the fragile Rmax:
