Should I make any pressure changes due to the increased weight?
You are already running at the pressure needed for your rig up to it’s GVWR... it’s maximum allowed weight.
The ride may be harsher than necessary, but is ‘safe’ up to max weight.
Weighing your coach to insure you are under max weight - or to get a ‘better’ (from ride perspective) tire pressure from tire manufacturers tables based on actual weight is a good idea...
I was surprised how close to max I was on one of our 3 month snowbird trips... Carry less stuff for shorter trips.
