Sure there's plenty of them...unless you're referring to the cab being stretched...only a couple of those and they aren't desert vehicles. But here's mine with stretched wheelbase/trackwidth...and a-arms
I'm sorry let me re-phrase my question. I was talking about taking a hard top body and widening and stretching the body 12"x12" and retaining the roof. I was thinking about having one done and/or attempting it myself and build a prerunner out of that.
I have thought about doing this. I would make it a convertible. Widening the compound curve roof would be unfeasible. If you are real good with sheetmetal, you could make a whole new roof with a big English wheel.
