Most of the diesel pushers we sold had air suspension. We had very little trouble with the systems. The main problem was the height sensors. This was easily taken care of with a simple adjustment. Keep in mind one thing. When you are reading about problems in IRV2 or motorhome magazine, You never hear from the thousands of people who never have problems. Most people never write about how great their rigs are doing, They only write in with a problem.
