The members here who help out with their towing expertise will be best able to help you out if you could give them the tt and weight info of that particular tt you are interested in. Although willing to share their time, many don't have time to find the tt that could ultimately work for your tv.
Otherwise, not being a tow expert, we once upon a time towed with a 3500lb max tow mini-van. Our 17' Casita was at about 3100lbs loaded (this didn't even have black/grey tanks or the bathroom). Personally, I wouldn't recommend anyone else tow this combination. Also, our mini-van had a max tongue weight of 300lbs (the reason we couldn't get the bathroom with that model as it was too heavy on the tongue); definitely not good going over the tongue weight! Additionally, if you max out on the tongue weight on your mini-van, you aren't going to be able to safely add additionaly passenger and 'stuff' to the van while towing.
