I used to pull our pop-up with a Windstar. Never had a single problem. Tow hitch and wiring was after market and loved it.
On your trip, do you plan on spending a couple nights in each location. Setting up for a single night's stay only to tear down in the morning will get old real quick. My suggestion is make sure you plan to stay a couple nights at each stop to make it easier on everyone.
We currently have a hybrid trailer and took a month long trip across the country two years ago with out 3 kids (12, 13 and 15 at the time). Highly recommend the trip! Your kids will LOVE it!
