Towing challenges with flagstaff 25FKS

Not only new to RVing but posting on forums too. We have maxis trailer tires that we put on new. We thought that would help the sway. It didn’t. We pull at a max speed of 68 MPH most of the time 65 and 60 in the wind. The current truck squats a lot when attach the TT. We have a lot of experience pulling boat trailers and low to the ground box trailer (high school band trailer). and never had one that will sway. I think we have the sway under control as long as the weight distribution hitch is on.
We do load the bed of the truck because the camper has a slide. We put our bags and food in camper. The bed of the truck has all camping stuff.
We check tire pressure s for both truck and TT before and during all trips.

Trailer tires shouldn't impact sway in any significant manner (unless they are wildly undersized or somehow obviously defective).

60-65mph should be doing better than 7mpg. We get 9-10mpg pulling a 7500lb trailer with a 2008 F250/V10 (which is known as a gas guzzler). What gear and RPM are you running and is it holding the gear?

If you have a WDH, of course, you always use it. It makes no sense not to.

It would be a good idea next trip to swing by a CAT scale. You don't have to be a trucker to use them. It's usually around $14 to weigh and re-weighs are around $2.50. Weigh it loaded with the WDH in place. With the WDH disconnected and then just the truck by itself. That will tell you a lot about what you are dealing with and are you over the trucks limits. Youtube it before hand and there are several videos going over how to do it.
