Bucking motion when towing

New to travel trailers. I have a 34 foot Heritage Glen, pulling with a 2015 Navigator. I'm getting a bucking motion whe getting to around 45 mph. Using a weight distribution hitch and one friction sway bar. My front wheel well is within 1/2 inch of when unhitched, but rear is about 2" lower than front. Do I need to go up another link on my chains or back off a link? My truck has load leveling shocks. Does this affect anything. I have a lot to learn!

P metric tires or LT's?
Coil spring suspension on the rear?

Hitch bars up a notch too far?

The only way to really set your hitch up is to have the TV and trailer on a flat level surface, then start adjusting links, tilt of the hitch and eventually the height of the hitch.
Takes a couple of hours of turning wrench's and adjusting to get it right.

Navigators have rear coil spring suspension which will make it bouncy regardless of a weight distribution hitch. If you plan on towing quite a bit you may want to invest in a set of air bags for the rear suspension. they have systems with on board compressors and a magnetic height sensor that pumps up the air bags when the suspension squats.

Tires ..... Are they those round black things that my truck sits on?? P Metric or LT out of my knowledge base. Hankook DynaPro HT. I believe these are P Metric based on a quick google search. Is that a bad thing?��

the tire size is printed on the sidewall of the tire, it will say something like P255/75R17/ a P metric tire has a low load rating..meaning the amount of weight it can safely support. A tire that says LT255/75R17 is a heavier duty tire, the LT meaning light truck, which usually has a load range of C or D or better. Lt is best for when you are towing things.

Yeah those aren't tow rated tires, those are passenger rated. unfortunately you may have to bite the bullet and get 5 new LT tires, don't forget the spare.

So is that an indicator of the strength of the sidewall? And would that make it bounce more? Sorta makes sense if there is too much give in the tires and the coils.
