Full sized all wheel drive transit 250 or 350. Super popular platforms. A lot of people lift them for a little bigger tire. They all have tow capacity and the high top ones you can stand up in. I’ve seen inside them all. They go from basic with a bed and a battery powered light to all built in with full power, generators, stove tops, water, diesel heaters etc. They’re cool.
The quigley 4x4 conversions are cool, but unless you plan to do real actual off roading, you don’t need them anymore since Ford put out the AWD transits.
Alternately look at Sportsmobile. They make some cool converted 4x4 Econoline vans but the Econolines will all be older vans now.
This one was in recently. It’s all wheel drive and a dually.
