Not the doom and gloom posted thus far. I'd say doable but not ideal.
People have done far more with much less and vice versa.
Would not be my first choice, but take er easy and it'll pull that little camper around for a long time. I'd def look into additional trans cooler and idk if they make air shocks or something to help the rear suspension, but see how the wdh loads the van up first.
By not ideal, I mean the van is set up and geared towards people hauling, not having an anchor hooked to it. My comfort level would be inversely proportional to the number of miles towed. Local trips, occasionally, let er rip. Regional trips, long distances, east coast mountains, not so much. Running through the Rockies and up to Alaska....find a better tow rig.
