We have a 2004 Ford F150 super cab, 5.4 liter V8 with towing package. It has a 355 rear axel ratio. GVWR is 7050 and towing capacity is 8500 lbs. We are now looking at a 2007 Coachmen Chaparral Lite. It is a model 267RLS with a baseweight of 6315 lbs. The brochures all say these lite fifth wheels are 1/2 ton towable. We live in Kentucky and will be RVing from here to the pacific. Can we safely tow this? Rockwood also has a new ultra lite fifth wheel model 8265SS that they say we can tow. Your help is greatly appreciated.
