How to tow travel trailer with 2 adults, 3 kids, and 2 dogs

I definitely agree with a van as your tow vehicle. Two adults, three kids, and two "medium sized" dogs, I don't think your passengers would ever be happy on a long trip. Some of the E350/3500 vans are rated to tow up to 10,000 lbs depending on the model. And room for the kids to stretch out and nap on long trips. Never towed with one, but used to use Chevy 3500 15 passenger van for 6 adults and 3 kids and all our luggage on yearly 750 mile each way family trip to Colorado and back. Worked great.
