Yeah, being able to stand up inside would be nice when putting your pants on in the morning! I was thinking of replacing the rubber snubbers on the bottom of the rear doors, I was going to make some adjustable ones that would help support the door with the spare tire and possibly keep the doors from rattling. I have even thought of welding up the rear doors completly this way I could put a closet across the back, does anyone really use the back doors for anything? I also had thoughts on buying a slide out shelf like you see in some pick up trucks and mount my bed to it, then you could slide the bed out and sleep outside on nice days, I hear they bolt to the floor and hold a lot of weight...... I dunno just thinking! even if you built the bed inside above the sliding rack you could still have storage boxes on the rack and then it would be real easy to get to stuff! just slide it out!
