I am going to try lower pressure tomorrow and see what affect it has.
Also note that I removed the old CRT style TV and all associated electronics and the rear passenger chair from this unit which lowered the front axle weight by an estimated 350-400#, Not much but it all counts.
This unit has a large water tank in the middle of the chassis, 75 gallons worth, and I never travel with it full unless I am dry camping which would be rare for me today. No sense in carrying weight you don't need.
I am in contact with a member of the forum that is very helpful with lots of experience with tires.
I do have Ironman tires, like new. size 245/70R 19.5.
The federal label inside the coach says max pressure on both axles is supposed to be 85 PSI and I am loaded medium weight, I think.
When I measure the pressure on the front I found that the pressure was over that recommended at 90.
So tomorrow I will lower the pressure and even them all out and take a test drive.
Somehow or the other I had in mind that the pressure was supposed to be at 95 PSI, maybe from what the dealer told me when I got it, and they could well have been wrong.
Anyway, I will check all the pressures all around and level them out at 75 as a starting point and see how it drives.
From there I will have someone experienced check the suspension for wear and possibly have some new shocks put on it.
Hopefully this will be a cheaper fix to the problems.
Thanks.
