MM:
Welcome to the forum, you'll find a lot of helpful folks here willing to lend a hand.
Thanks for indicating your interest in learning how to figure out what your vehicle can tow, and I think it's implied that what you really want to learn is about safely towing your trailer. Too many times someone simply asks, "Can I tow my ??? trailer with our ?????" It's not that easy. Each situation is individual. In order to really know the answer, and be confident that you're operating in a safe manner, the right questions have to be asked and answered.
I'm attaching 4 pages from this year's July-August edition of the Escapees magazine. This is an article entitled, "My Truck Pulls it Just Fine". A real pearl of wisdom from the article is this statement, "The ability to tow something is never the problem." As a friend of mine said, "Give me a ball hitch bolted to a little red wagon, and just a half degree of incline, and I can tow a 40 ft trailer. But, stopping it could be another matter."
This article includes links to two online calculators to allow you to calculate your vehicle's towing capacity.
Please read through these pages (assuming I've attached them correctly) and you'll learn a lot. Ask more questions if you need to, this is a friendly group!
Travel safe!
