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

Since you are totally new to RVing, I suggest you go buy a book on RVing and camping. It will explain pros/cons of each style, weights, safety,
equipment, techniques, towing, capacities, etc.

AFTER you have read that and done MORE research online, THEN go looking at units. Don't buy the first one your wife thinks is pretty or is the cheapest.

Do your research and be patient. Your will be money ahead...and happier!
