Thanks for the pic. That’s exactly the way the F150 looked with it. Which lift kit did you use?

It is a very common misconception that running trailer tires at less than their maximum inflation pressure is better because it is "easier" on the tires giving that "cushion" you mention.
In fact that is precisely incorrect.
If you want a cushion, inflate them to the maximum of 80 PSI. That is where the tires need to be to provide their maximum load bearing capacity.
Then you will have that cushion and it will be easier on the tires.

I wasn’t trying to be easy on the tires at all, but chose an air pressure based on the manufacturer’s chart that gave me a significant step in load carrying capacity (cushion is the word I used ... maybe not the best word).
The other contributor to deciding on 65 PSI was the ride of the camper. One of the “advantages” of pulling it for 16k+ miles with an F-150 is that I could feel absolutely everything going on with the camper as it went down the road. Fortunately, I never had anything significant go wrong while towing, but I have no doubt I would have been able to feel it immediately.
80 PSI (for a 9000 lb. load) made it feel much more harsh on rough roads, especially at interstate speeds. That is the primary reason I backed the pressure down, was to add a little shock/vibration dampening (cushion might be a good word) for the camper (which is constantly in a state of repair already).
The “downside” of the 2500HD is that now, just like everyone has said on other topics, I really don’t know it’s back there anymore. I can’t feel anything going on with the camper or the road. Everyone says that’s a good thing ... time will tell. It’s definitely different now.

Im working on resolving the same issue with my new 5er. The added concern I have with my 2019 Rockwood is that it came with a 3-step MORryde StepAbove so installing a lift kit would mean having to extend the step’s feet further making the first step that much higher off the ground.

I’m going to shoot the tire temps several times on my next trip in a couple of weeks, then decide what to do.

I looked at yoru steps, and they rest on the ground at the bottom. I think they make a 4 step model and if that one is too long then perhaps you could add something like this:

It is aluminum and the legs adjust so it will work nearly anywhere.

The biggest reason I bought the truck I did, was because it could be lowered. I looked at all big 3 and GM was the only one in the newer models that could be lowered. I had the dealer lower it 3" when I bought it. That was enough to make the fiver tow level. I didn't want to raise the RV.
Of course it doesn't look as cool down at the local Mickey D's since it doesn't take a step ladder to get into it, but it works for me.

I did that on my most recent trip. We stopped after about 1.5 hours and I shot the temp on all 4 tires and hubs. The rear drivers-side hub was quite a bit warmer than the other 3. It was about 50°C or 122°F with ambient temps in the mid-20s (°C). So I'm taking it in to a local trailer shop on Wednesday to have them do an "annual inspection" and hand clean/re-lube the bearings. I've lowered my 5th wheel hitch to its lowest setting at about 16" above the bed but I still need to go to where the 5er is stored to confirm the bed wall clearance is sufficient. At the mid setting I have more than 2 fists width of clearance - maybe 9-10 inches.
I have another 3 hour trip coming up on Sunday so I'll check it again then to see if it made any difference on my trailer.

Did you lower front and rear, or just rear?

Lowered front and rear. Front 2" and rear 3". Makes it easier to get into as well as making the RV ride level.

Just to update on this, the trailer shop said there was nothing wrong with the rear driver’s side bearings and it was likely just that the brakes were dragging a bit. We’re heading out tomorrow for a week so I’ll have a chance to see if there is an improvement after they worked on it.
With my B&W Patriot 18K hitch at its lowest height setting (I lowered it 2 bolt holes) I have about 5-6” of clearance above my tonneau cover that sits 1.5” above the bed rails. It’s much closer to level now.
