Not exactly true. For a travel trailer, you'll need to use a weight distribution hitch. For a correctly adjusted hitch and loading in the camper, an 'average' weight distribution is 80% of the tongue weight on the truck and 20% on the trailer axles (hitches own weight accounted for).
So with 1050 lbs on the hitch and a WDH, you should be putting around 840 lbs on the trucks axles. So you should have 1300 lbs - 840 lbs = 460 lbs left for people and gear. Of course there's many factors so go to the weigh station and make sure!

If a gear swap is the direction you're going to head, I would start checking with local wreckers....My comment wasn't intended to flame you, unfortunately I read a lot of these posts in the RV forum I frequent....

tow weight
I appreciate everyone's help. For right now going to look for a TT within my tow range but still pursue changing the rearend to 3.55. Not in a hurry for the TT but looking for something bigger with four grand kids. Thanks again.

I wouldn't go 3.55. I'd go 3.73 to make more of a difference as it's not cheap.

Take a look at the Keystone passport. They might have a floor plan that you would like with a weight that will work for you.

Well the Ford Dealership will change it out to a 3.55 rearend. $2300 but it is cheaper than a new truck and will still be under warranty. Looks like I will be getting that Rockwood 8315BSS after all Thanks everyone and I hope someone learns from my mistake.

Did you ignore my post above? Basically it said that your axle ratio and your tow rating is not your problem. Spending money on shorter legs in the differential is not the fix to increase the weight of a TT you can tow without being overloaded. The GVWR of your tow vehicle is your problem. You will not be able to tow a TT that grosses anywhere near 8,100 pounds without exceeding the GVWR of your F-150. I mentioned that about 5,000 pounds wet and loaded weight of a tandem-axle TT is about the max you can expect to tow without exceeding your truck's payload capacity, which is based on the GVWR of the truck.
8315 BSS
(dry) Hitch Weight 905 lbs.
(dry) Ship Weight 6,843 lbs.
(dry) Cargo Capacity 1,507 lbs.
GVWR TBA, but normally it’s shipping weight plus cargo capacity = 8,290
So figure 8,000 pounds for wet and loaded trailer weight, and hitch weight will be around 12 to 15% of wet and loaded gross weight, so count on 1,200 pounds for hitch weight (tongue weight).
7,200 GVWR minus 1200 tongue weight = 6,000 pounds remaining for your wet and loaded F-150 full of fuel, passengers, tools, jacks and WD hitch. Pets? Campfire wood? Because I’m overloaded with my TT that grosses 4,870 pounds when wet and loaded on an RV trip, I can guarantee that you’ll be overloaded with your 8,000 pounds TT too.
