Front tire pressure

I have monaco 36ft dp. Dealer said 115lbs in front tire. When i go over a bridge or any bump ... Wham !!!! It is loud. My rv neighbor has 38ft monaco dp. He weighed his ... 10,000 lbs on the front and closer to 18k lbs on the rear. He told me to take front to 90 lbs and it will be night and day going over bridges. Good advice ?

If you are running original size tires, what does your tire pressure label say?? I suspect it's NOT 115psi, that is probably the MAX pressure rating of the tire and is only required when loaded to maximum carrying capacity.
If tires are not OEM size, then weighing and looking up the required pressure is the best solution.
