Re: 92up Cutaway cab rear wall
I own a 1990 E-350 ex U-Haul 17 foot moving van and a 1992 Braun 14 foot Super Chief ambulance. The U-Haul box and cab back wall are separated by an air gap of about 3 inches. When driving down the road, we discovered when stretched out full length across the front seats (persons up to 5'7" can sleep this way without taking out two screws for each door arm rest for additonal end clearance) that the forward projecting "mother's attic" forward box projection moves around noticeably compared to the position of the cab. Maybe that flexing is why U-Haul designed these with the gap between the cab and the rear box. The box and back wall are NOT steel. They are fiberglass. Mine now has 125K miles on it and it's still like new. Seems to me their design works well for what they wanted. But the interior box height of 7 feet 2 inches is way more than I need. I'm considering lowering the top by a foot or so to be more like U-Haul's earlier moving van box designs. Some were as little as 5'10". Think of how much wind drag each unnecessary addtitional inch of vertical projection adds. The U-Haul box is wider than the Braun ambulance. I'm considering ways to add a passage way between the U-Haul E-350 cab and the box. That gap makes the project much more demanding than it would be if this were a single wall design like the ambulance. Any suggestions as to flexible rubber accordian door material sources for filling the perimeter of this passageway gap would be appreciated.
Parking the U-Haul next to the Braun ambulance surely shows a wild contrast. By comparison, the Brawn is low and sleek appearing, only partly because the 1992 new cab body style appears sleeker. I've parked it next to other E-350 ambulances and it's larger than them, but it's shorter, narrower and less tall then the E-350 U-Hual. My 14 foot (not the much more common 12 foot designs) Braun is the largest E-350 ambulance I've ever been able to find, and is now only available on the 450 chassis, but it's small compared to the U-Haul. Not only is the U-Haul about 10 inches wider (just from memory), but the box stands much higher. Both have similarly low loading height. Both have raised floor projections to accomodate rear dual tire clearances. The cab to rear passageway in the Braun is wonderfully executed with a nicely fitting hinged door. I wish my Braun were as wide as the U-Haul, and I wish my U-Haul interior standing height were as low as the Braun, which is still plenty. Obviously the ambulance cab to box passageway is superior to anything that's possible with the U-Haul's 3 inch open space gap.

Lightest 1995 Standard Cab PowerStroke F-250 with factory "Camper Package," no AC, 5-speed, Conklin ParaSynthetic Oil with MolyLube, oversized 10-micron filter, Randy's Ring & Pinion aftermarket 3.07 ratio running in Royal Purple, Stanadyne always in fuel, tires @ 100 psi, nearly zero friction brake adjustments, 203 degree thermostat enables higher engine efficiency than 195 degree units, front end precisely aligned with minimal toe-in to reduce friction, lowest rolling friction F-250 I've seen. 2-axle trailer tires run 110 psi generating less rolling friction than lower pressure tires. Infrequently carried slide-in camper is an older all-hard-side Siera pop-up. Hard sides seem more secure than canvas connected pop-ups when up and never have canvas mold problems. Pop-ups push less wind than fixed height slide-ins.
