The truck has a heavy weight trailer tow package with 3.73 rear end ratio. Any opinions on whether this would work as a match for towing?
First, don't fool yourself by using the dry weight of the trailer. Nobody tows a dry trailer. Almost everybody will have the trailer loaded to almost the GVWR of the trailer by the middle of the third RV trip.
The GVWR of that trailer is 4,759 dry weight plus 2,829 carrying capacity, for a GVWR of 7,588. Count on the trailer grossing 7,500 pounds. The dry hitch weight percent is 12.3%, so count on it being at least that much when wet and loaded for the road. I would use 13% for your purposes, and it can easily go up to 15%. So count on hitch weight of around 975 to 1,125, or rounded to 1,000 pounds.
It sounds like your truck has the max tow pkg but not the HD Payload pkg. So your GVWR is 7,700 pounds? Your tow rating of 11,000 pounds is Ford's wet dream because it ignores hitch weight. You can pull
a TT that weighs over 11,000 pounds, but the hitch weight will cause you to be overloaded. (My F-150 EcoBoost is overloaded over the GVWR of my F-150 with my TT that weighs only 4,870 pounds when wet and loaded on the road, but my GVWR is only 7,100 pounds because I don't have the max tow pkg.)
So it sounds like that trailer will be a good match for your tow vehicle - provided
you don't haul much weight in the pickup. Two adults and two labs plus a few pounds for tools should be no problem. You'll know for sure how much wiggle room you have for more weight in the truck after your first trip across the CAT scale in the middle of your first RV trip.
But if you want to be certain before you spend the money on that trailer, then weigh the pickup before you buy the trailer. Load the pickup with everything that will be in it when towing - people, pets, tools, spares, options such as bed rug or spray-in bedliner, and the shank/ball mount for your weight-distributing hitch. Go to a truckstop that has a CAT scale, fill up with gas, and weigh the wet and loaded F-150. If it weighs less than about 6,700 without the trailer, then you'll probably be okay. If it weighs less than 6,500, you're good to go buy that trailer.
We would use a weight distribution anti sway hitch.
I hope so. Any TT that weighs more than 5,000 pounds requires a WD hitch. I would not tow a trailer that grosses more than about 3,500 pounds without a WD hitch.
