Got to be a front wheel drive. And simple. just basically weld a Toronado subframe to the A frame of your favorite trailer and drop a pickup cab over it. OK, maybe that's oversimplified, but not by much. The drivetrain should be able to handle it, there are a ton of those old GMC motorhomes still kicking around the country 40 years later with the Toronado drivetrain, anc you can pretty much buy anything for it from Applied GMC. What a cool idea.
