The air gauge failed on my 2000 Safari Continental. There is a new presentation on how the problem was corrected and the air system improved. This was not as simple as just changing the dash air gauge. The RV specialists had incorrectly connected the air lines over the years and the result was damage and a compromised system. The presentation shows how the system was upgraded. Just follow the menu under branches-repairs-air system. Please leave a comment on what you would like to see as a presentation and I will factor the interests into selecting the next topic. All the items in the completed branches of the project tree are available.
