We just purchased a new 2017 Forest River Salem Hemisphere 299 RE. Dry weight=7,439 lbs, hitch weight=730 lbs. We own a 2013 Ford F-150 XLT 1/2 ton with a towing capacity of 8,000 lbs and a 3:31 re...
Not enough truck. The 3.31 axle will kill you, plus the payload and tow ratings will be maxed out, if not exceeded.
