I added the Firestone Ride rite system to my 1999 Tioga Montara several years ago. was the best investment i ever made. It was worth every penney I spent on it. The ride was much better. sway was controlled and could carry a little more weight in storage. I generally carried about 85# of air in mine.
When I bought Coach House motorhome a few months back it was equipped with same system.
To save money you can air them manually with valve stims like your tires or you can get on board pump unit with gages and adjust them from drivers seat.
Also note you can raise the back end of the coach a little and it will not drag as much in drive ways.
In my opinion you can't go wrong with the ride-rite system, by firestone, or the air lift system
The system I installed on my old Tioga I installed myself. But that was when i was 65 years old
Now i will turn 79 this month and I don't think I will install any more.....!!!!!HaHaHa. My wife and kids would try to catch me and kick my Butt.....!!!!!
Good Luck
and Happy trails
