What can I tow with a Ford Freestar 4.2L V6 AdvanceTrac

We are interested in purchasing a travel trailer. Like the rest of the members in this forum, the TrailManor seems to be the perfect trailer. Our wish is to get the largest trailer possible while still being safe. The TrailManor dealer near us told us that a fully loaded 3023 weighs about 3200 lbs. We like that trailer the best.

We intend to use the trailer to camp in Michigan in surrounding states with driving trips of no more than 3 - 4 hours over relatively flat terrain.

Our 2004 Ford Freestar has a tow rating of 3500 lbs and a maximum tongue load of 350 lbs. It does have the 4.2 L V-6 and the Advancetrac (ABS/Traction control) feature.

The Ford dealer, after consulting with his aftermarket tow specialist, didn't seem to be too concerned with anything under 3500 lbs. In fact, he suggested adding a transmission cooler only if I planned on towing something more than 3500 lbs. (I think this is bad information.) He suggested using a weight distribution hitch.

A local RV dealer (not the TrailManor dealer) told us that we didn't need to worry about the hitch limitations as long as the trailer weight was within range. (I also think this is bad information, but wonder if a weight distribution hitch allows you to exceed the 350 lb. tongue load.)

I've read enough about GCWR and all other formulas to be thoroughly confused. On the internet, you can always find someone who will say something that will validate your thinking.

My question is whether anyone is towing a TrailManor with a minivan and, if so, which TrailManor they are towing, what are their experiences, and what modification did they make (or would they make) to the tow vehicle.

Also, if anyone thinks I am absolutely nuts to be considering towing a TrailManor with a minivan, please let me know. Although the TrailManor's are fantastic, I will not risk my family's safety.
