I thought the window was too small too.... even from the inside. I did see inside this unit, but that was before the owner said I could snap off a couple of pictures....while it was being serviced I took the liberty of poking around. I sure did get a lot of good ideas from this bus. When I looked into those storage bays, and looked up, I saw he had stuffed insulation between all the floor joists, silver backing faced down, and a couple runs of sliver metal tape to keep things from falling down. It was simplicity at it's best!! All the plumbing was inside these insulated compartments too...
I sure didn't like that GMC's method for servicing the motor. The bed was on gas lift shocks, and flipped up to reveal the rear engine. The radiator was in the very rear, so the mechanic had to crawl under the bus and stand up inside the engine compartment....they flipped open the bed so he would have head room in there!! On look at this set-up and I learned to appreciate my Saf-T-Liner a whole lot more!!!
As for the cargo doors, the other side looks a little better as he's got the stainless all the way down (and that would be my bus in the background)....
