Hmm...well, the 3.3 might be a little light considering that the Grand Caravan is a biggish minivan, and so it has its own weight to consider. Looks like the max tow capacity is 2,000 lbs on that engine size, which is indeed problematic, even with a popup. Mine weighs 1,800 lbs empty, and that isn't much of a margin, I'm afraid...
Time to shop for a new tow vehicle before picking out the perfect camper!
