Front tire pressure

tires say 110 when cold ... I run my 26,000 lb unit at 100psi all the way around .... handles great and smooth!

You should look under the car to see if the suspension is at its end and hanging almost against the silent blocks , then its a matter of stronger suspension.
If suspension is neatly in the middle , then recalculate the tire pressure with my spreadsheet for that you have to weight at best, but in lack of that , give the GAWR's front and behind and the specifications of the tires like maximum load and needed pressure for that read from the sidewall . also give the speedcode if you can find it( mostly N for 140km/87m/h ) .
Then I will give a picture of my filled in spreadsheet in my answer.

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.

Best advice is to weigh your rig and set your pressures accordingly! (He probably is right in the fact that you are running to much pressure.)

I run my front tires at 120 PSI inflation!

I run mine at 90 all around.

With my weight I can actually run at 85 according to the Michelin weight chart for my tires.

115 will beat you clear to death. Dealer pumped mine up to 110 one time and I drove about 150 miles that way. BAD. It also causes poor handling when they are over inflated.

Lowered the pressure the next morning to 90.

Might also want to check your shocks. If they are the original Monroes, you will want to be changing them.

Get the weights of each corner and go to the tire manufacturer Web Site and inflate per the instructions.

To weigh and check the weight vs pressure tables for the tire is good advice. Using 90 psi because it is right for his weight and tire, not so good for you.
