First, i did search, i found a formula, but my math sucks! I am looking to purchase a bumper pull travel trailer. Nothing too crazy, 25-28 footer. I have one 4wheeler and i am looking to purchase another one as well. My question is, at 700 pounds a piece, would i be overloading my trucks capacity hauling 2 quads on a diamondback style cover and towing a 6-7k trailer?
