Wonder what the driveline is like in this? Front wheel drive?

I wonder if it is a twin screw with a tag?

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.

where did you find that picture? I'd like to see if I can find out more about it/

It was just a random pic on facebook so there was no link that I could find.

Looks pretty cool.
