Hi, I am a 65 year old female who has never been camping or rving (except as passenger). I wanted to try the lifestyle but didn't want to invest a lot of money just to try it out. So I purchased a 22 ft. 1992 Tioga, Ford 350 with 50,000 miles on it. It bounces while driving and I have read about airbags on this site. Is that something that comes on the rv or something that has to be added. Would it stop the bounce or do I just need shocks? Also, the cabover has a squeak which sounds to me like rubber rubbing against rubber. Is there anything that can be done to stablize the cabover part to stop this annoying sound. Please any suggestions or recommendations? Thanks
