Towing Capacity

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 rear axle.

Do we need to move up to up a 3/4 ton with a towing capacity of 10,000-11,000?

R.V dealer informed us, the trailer can be pulled with a 1/2 ton truck, when distribution and sway bar kit is installed.

What is your opinion on this? We normally stay on flat ground, however we're looking forward to traveling cross country.

Thanks,

Your truck will certainly MOVE your trailer. On flat ground it may even seem good at 35 mph. But you mentioned a cross country trip. that means interstates, it means mountains, and unless your schedule is measured in years, it means speeds greater than 35 mph.

Look at the two primary numbers from your trucks specs.
Payload, this is all the weight pressing down that your truck is designed to handle. It includes all passengers, cargo both in the cab and the bed, and the tongue weight from your trailer.
You didnt list your trucks limits but it likely is around 2600-3000 if you have a standard cab model, it will be less with extended cab.
Towing capacity is all the weight your truck is designed to pull, it is based on your engine, transmission, suspension, shafts and frame components are capable of hauling, AND all the weight your brakes are designed to stop. On your cross country trip, crossing the Rockies with overloaded brakes will not be an experience you will want to relive.

When you look at the TT specs, look at the loaded weights, because empty is with no battery, propane, propane tanks, water, food, clothing or anything else. Loaded weight is at least close to what you will actually be pulling, actually having your trailerweighed is preferable, so you know what you are working with.
