Temperature outside was 75 to 80 and TPMS said tires were between 94 and 100 temp.

You have a nice heavy duty 14 ply tire. 82 psig is on the light side even if you were empty INMHO, I would to up to 85. Your sidewall max cold psig should be 110
I ran my F550 with similar tires at 110-115 psig but usually had 16 ply due to the heavy tandem trailers we towed often. A lot of cattle on a 32 foot trailer is a bit heavier than an RV for sure.
No issues with handling or tire wear either when running empty but you did notice the potholes
