Thanks for the update on the value stem extenders. I haven't noticed anything coming loose on mine...I will pay closer attention to them. I will also look to fortify the LPG tank shield as well.
Regarding the shocks and airbags, keep in mind I did all 4 shocks before the airbags. From my personal experience, the shocks made a huge difference in highway driving (rough roads, uneven roads, you name it). Especially at higher speeds...I use to slow down a bit when encountering rough roads...now not so much. The shocks even reduced the side to side rolling of the coach by a lot. My wife was amazed by how much the shocks made a difference.
Now for the airbags, they can make the back more stiff depending on how much PSI you have in the bags. Last trip my wife played with the PSI and settled on 25 PSI. Next trip will have more weight (in the coach)...so I will let you know on the PSI adjustments. One thing I noticed is the airbags reduced further the side to side rolling of the coach.
I was told by numerous people to upgrade shocks for improved overall ride and airbags for more stability (windy conditions, etc.) and reductions in side to side rolling of the coach. So far my personal experience is that...however I did not do the airbags before the shocks...so I honestly can't speak to the benefits of the airbags by themselves.
Hope that helps...now have 7,800 miles on the coach.
