For the super vanners here's the ultimate delivery van. Three skids on board plus 3 feet of personal space in front of that.

One other real negative - the translucent roof would cook you alive in Laredo!!!!
Is your whole roof made of translucent material, or just a strip down the center? My mental build of a cuber with a translucent roof would include 1-1½ inch foil backed foam insulation board. Over the living area I would include an insulated, hinged "door" about 16"x16", depending on roof bow distances. This could be opened inward (downward) to allow natural light in and some heat on cool days.Not a sprinter owner ..but the translucent roof if properly insulated is warm in winter and cool in the summer.....just got done insulating my cube roof yesterday and it was 95 degrees here in Iowa ...big difference once done ..
I did a Manhattan delivery. ONCE!! LOL!! Actually wasn't that bad. Right down on Water St. I napped until the drop (office) opened and woke to about 150 officers all around me. Apparently they had/have meetings right out on the sidewalks! Who knew???
