Shock absorbers BAD ?
We are just finishing a month on the road and are on the way home. During the our trip found many states with bad roads with pot holes, bad bridge entry and exits and bridge surface.
It seemed that the motor home would hit these bad road conditions very had.
I do not know how a RV with air bags would act with bad shocks on rough road conditions.
The RV does not bounce like a car with bad shocks does.
Please give me some advice.
Thanks
Dwight

As what you mentioned, the shocks are working properly; you might be over inflated on your tires, try to drop them a few pounds, ± 5 lbs, you will feel a nice difference.
The air bags just replace the conventional coil spring suspension or they are addition to; the same over inflated tires will give you a rough ride, air bags or not.

Are your air bags inflating? Have you ever had coach weighted for proper tire inflation?
May need new shocks if they are the originals.

If the shocks have fluid running down the shock they are bad. You can also take the bolt out of the bottom of the shock and move the shock up and down and you should feel resistance.

Beowulf2 mentions that the rv does not bounce, so this means that the shocks are good ! Either orverinflated tires or air bags is the cause for the rough ride.

Thanks for the comments. Finally got home and got the computer up and running. I did call TCI about the tires and they calculated the tire pressure to be 105 to 110 psi. I dropped the front pressures from 120 to 110 and it did make a differance. The tires are one year old Michelins 275 R70 22.5 and if I remember the old tires were 270's. Air bags look fine have not really checked the shocks. However, I lost a front hub cap ( first in four years ) and developed a refrigerant leak in the rear AC unit. "I blaming the bumpy roads for the leak" HA HA The trip was over 4,000 miles and if this is all the trouble if feel lucky.
Thanks,
Dwight

You really should get the coach weighed and then set the psi to the manufacturer's specifications plus 5% as a safety factor. Individual wheel weights would be best, but even axle weights from a CAT scale are better than nothing.
