I've seen a T100 fer sale on CL or
ebay that someone made a custom sleeper fer the long bed that attached on the back of the window. It didn't look all that great...
It looked kinda like a bad tool box hybrid...
I guess you could cut a camper top so it's short and modify that so it would do the same thing...probably cheaper, too!
I guess if yer gonna go through the deal of pulling the entire cab and bed off the truck (including wiring and such)...you might as well buy an extended cab.
I believe the fuel tank got switched over from the passenger side to the driver side in 1995...so that's something you would have to contend with as well.
