Hi, My husband and I are looking to purchase a used travel trailer this summer. We have a Ford Explorer Sport Trac 4WD with a V-8. It says we can pull 6,640. I know we can't max that out but I am guessing we can pull like a 22 ft Prowler that is about 5,400. Or maybe that's still cutting it too close. The dealer says you just need to go under 1,000 from what your vehicle guide says you can pull. However, dealers say alot of things. I have tried looking at all the formulas for figuring out what you can tow and it really hurts my brain!! I am not an idiot but there seem to be so many variables. My main concern is the short bed that our truck has. Is this going to be a problem with pulling a travel trailer? What sort of safety concerns do we have with our short bed truck and what are some things we need to look for in a trailer or in hitching equiptment? Thanks a bunch!
