Help deciding on new tow vehicle

I second the van idea. I did it for 22 years with no regrets. I only sold mine because I am down to one kid at home now and I wanted 4 wheel drive. The Chevy's and the now discontinued heavier duty E-siries vans are built on truck chassis and pull like a truck. The also burn fuel like the older trucks. The new Transit is built more for hauling people and cargo and fuel economy at the expense of towing but can be configured to pull 7500lbs which should be enough for your trailer and is getting great reviews. It is selling great too, that should tell us something.
