Will be looking to upgrade my KZ Coyote 23CT (GVWR 5,512 lbs) and am wondering what I can pull with my new Ford F-150 Lariat that came with a 5.0L V-8, towing package. The F-150 pulls this KZ with ease. Research indicates I can pull 9300 pounds but I wouldn't go any higher than 8,300.Lots of discussion about 1/2 ton towable and limits. is there a website that I can plug in my vehicle specifications and get a list of possible RV's that I can pull?
