Tech rep for HWH, set up CC's leveling and slide out systems. Two major topics: Leveling sets and slide outs. (Excellent presenter!)
Hydraulic jacks versus air leveling systems. Intended to be a relatively fast way to level the coach. Less stable, and not as much correction.
Air leveling system: Park, set brake, leave engine running, tap it twice, coach will level itself on the way down if possible. Yellow lights indicate low portion of coach. Once they're extinguished, red light stops flashing and goes steady. From that time it sleeps for 30 mins, wakes up looking for yellow lights, makes correction if it sees it. After that, it sleeps until after one yellow light comes on. NOTE: Keep engine running while leveling! It will take a LOT longer to level after the engine is shut off. You'll only have a very small compressor working for you.
OK to set parking brake, leave engine running, hit dump, when down immediately hit level button twice. You'll level at a lower point (engine still running, so it levels "up").
Ride height control valves -- these are completely different from the leveling system that HWH installs. Older height control valve is filled with thick gel. The gel thickens over years, and get "lazy".
If it's parked for a month, you'll lose air -- and quite possibly unevenly from corner to corner. Okay to dump it all the way down. No effect on air springs by either dumping or leaving them filled. Note -- you can add hydrolic jacks to existing air leveling system, and use the same computer leveling systemt that's already installed.
How to determine level: A disk is used as a controller. A tolerance of 1.5% degree -- about 3/4 inch -- or 5 inches from one end to the other of a 38' coach., and operates on mercury switches.
If ground is to uneven to level, what recommendations? Reposition the coach, or manually do it. The most difficult part to level is rear side to side. So first air the rear all the way up, then immediately go into computerized leveling. A good tip!
Nice features: With room "in", you don't have manually applied locking arms inside the coach. Country Coach units has a locking latch. Rooms are being pushed out with a tremendous force. These are the biggest, strongest slideout units in the industry.
New design for Country Coach will be significantly lighter, stronger, and eliminated much of the space robbing structure of the present design. Watch for them in the future.
