Hi being a newbe hear aand in rv'ing I see a lot of post's concerning towing with a half ton p/up I have a 2014 Ram 1500 with a 10/k hitch and with a 14150/bs GCVW my trailer is a 2007 forest river...
One other number to look for is your axle ratio. It'll be something like 3.55 to 1. The higher the first number, the better mechanical advantage for pulling. Your economy drops with the more extreeme number. For instance, 4.11 to 1 is great for pulling and will pull a house. Your top speed with really drop if you don't want your engine screaming. 2.91 is useless as a pulling gear. If your ratio is 3.55 to 3.73, you're right in the sweet spot.
