Have you seen the long-bed conversion of the Mega Cab (which only comes in a short bed)? I want one but no way I'm spending $75k on a pickup truck.
I've seen a picture or two somewhere, but I haven't seen any in person. One thing I think lots of these designers forget about (or choose to ignore?) is parking these monsters. I don't want a vehicle that I have to park at the outer edges of the lot then hike half a mile to get into the store. And forget about the gas mileage!
I guess I'll stick with my '87 Dodge a while longer. It'll most likely outlast me anyway if the docs know what they're talking about...
