Lots of good replies have been made. Your steering, even with a short body coach, need not wander excessively. Those responses suggesting you start with steering allignment and tire pressure inspection are right on. Unfortunately most wandering is caused by other factors. There are a number of after-market devices that can help control this from better shocks, sway control bars, and other items. I had a new 30' motorhome that also had excessive steering wandering. Contrary to suggested policy, I went directly to a steering stabilizer ... in my case the Steer-Safe... and the result was like going from night to day. White knuckle steering immediatly became one finger steering for me. ( Not that I'd suggest anyone steer their RV with one finger). I had no regrets in this and the coach steering performed fine the remaining four years that I owned it. Had I to do that over again I might have gone with the SaftyPlus steering stabilizer due to its more elegant design, but they all do the same thing ... and as an added bonus they can greatly help emergency steering if you have a front tire blowout.
