Hunk of Cheese,
do you have the tires properly inflated for the load that they're carrying? Some places just air up the tires to the max inflation pressure on the tire, but that is often times over-inflated for the specific tire & RV/weight combination. I know on our rig that gave a very poor (hard) ride and made steering a bit squirrelly, especially on rough pavement.
Argh. Yes, I have the tires aired properly -- I keep them all at 90 PSI, which is slightly higher than the tire manufacturer's recommendation for my weight. Tire mfr. recommends 80 PSI which is also the tire's minimum allowed inflation and I wanted to stay above the minimum.
When I first got my coach and took it in for inspection, the shop filled my tires to 140 PSI. Ride was so hard. I came back later after learning some stuff and tried to tell the guy he had made a mistake. The whole shop was immediately very angry, (I guess they had had this argument before.) and somebody sarcastically yelled at me "if 140 PSI wasn't the tire manufacturer's recommended pressure then why would they stamp it on the side of the tire?!". They waved away and didn't want to look at my PDF brochure from the tire manufacturer. Wow, that was frustrating.
De-airing the tires did help a lot with the squirrely but it's still there.
