Your vintage coach can and will drop or lean regardless of whether your aux pressure is 0 or 120.
When the key is off on your vintage coach the Norgren valves that are responsible for directing the flow of air to or from the air bags go to a position in which they lock whatever pressure is in the air bags in them.
So you dropping in the front of the coach is going to be associated with leaky front air bags, a leaky fitting at the air bags or Norgren valves or the Norgren valve(s) themselves. I can’t remember if you have one 5 port Norgren or two 3 port Norgren valves to control your front air bags, but start there and then check all fittings and the air bags themselves. Soapy water is a good place to start.
Norgren valves can leak in several ways, either through the valve itself, or sideways out the end caps. Either way they will cause the loss of pressure in the air bags.
Here is free advice worth every cent you paid for it: If you think or know your Norgrens and air bags and push in air fittings are original, don’t waste your time or spend money to get someone else to look for leaks. Replace the valves, air bags and fittings.
You also need to understand if your coach auxiliary air system is isolated from the Prevost accessory system because understanding your coach and its systems help with managing the coach and identifying potential problems. I’ll let Marathon owners add to the discussion if they want.

There are a handful in the drivers junction box for lights if i recall. The box on the outside right under the drivers window

No matter who answers one of your questions, there may be an exception.
It might be a good idea to start here(LOOK HERE) to get some background.
I’ll answer a few questions, some answers may even be close to correct, maybe not.
Disk brakes ? — My 2000 XLII chassis has disk brakes. They started earlier.
ABS braking ? — My 2000 XLII chassis has ABS braking. They started earlier.
12.7 S60? — Some late 1994 chassis.
2 piece (versus 4 piece) front windshields ? — I think your question needs to be narrowed down to the “H” chassis or the the “XL” chassis…I think, maybe.
Curved entrance steps, versus straight entrance steps ? — I haven’t seen curved entrance steps…that doesn’t mean that they don’t exist. Maybe this is another question that needs to be narrowed down to the “H” chassis or the the “XL” chassis. There are usually 2 short flights of stairs in the “H” chassis. 1 flight of stairs in the XL-XL2 chassis.
Do any of these buses come with tilt/telescoping steering wheels ? Should they ? — My 2000 XLII chassis has tilt/telescoping steering wheel. They started earlier.
There are a lot smarter Prevost historians in the group maybe some of them will fill in some of the details. Start in the link supplied above.
Your mileage may vary, objects in mirror are closer that they appear.
Best of Luck!

Yep, It sure is nice here on the Mountain. It was 66 this morning.

The pilot in question sent me a message this afternoon. We’ve never met in person, so I know him about as well as I know most of you. He said he was inspired to get a Twin Bonanza by our mutual friend, who was inspired by me. Therefore, he said, it’s my fault he landed on the highway. Small world.
So, I’m still trying to wrap my head around the flat towing issue. I know a little about driveline disconnects, and don’t want to crawl under something whenever I need to tow it or drive it. It sounds like many older cars can be towed in neutral without transmission damage, but a lot of newer cars need some sort of oil pump installed. Has anyone found a good reference for determining if an older car can be flat towed? Or are there certain clues/features/options I should look for that will cause me grief? I’d still love to get just one car if I can manage it.

The gauge is stuck…. lol

You guys should be commended for taking your coaches to a CAT scale and weighing each individual axle to determine your weights. I’ll bet that then you go to the web site for your tires to determine the proper pressures.
That’s much more prudent than asking Prevost owners on Facebook what tires pressures everyone is running.

Did it myself.
The black and silver is caliper paint.

Don you painted it your self or had someone do it for you?

Hello, Jimmie. This area area has gotten quite large since I moved here in 2005. It is a really nice area in which to live.
Charleston is a favorite of ours. Two of sons attended College of Charleston. Our plans were to make it over that way, possibly Johns Island, at retirement. However, we are going to take a wait and see about such a move for a little while longer. I am retired but Tammie has a couple of years yet to go.

My engine compartment looks ok, But Don went all the way,looks awesome, Craig Wickham did a complete job on his also, engine color my paint says Detroit series 60 blue, I don’t know which one is correct?

Do they need to be bedded. Good questions. They might have been pre-bedded. What does the vendor/manufacturer say?

I suspect with almost no charter bus travel or entertainers putting on shows Prevost needs every square foot of space for buses that would typically be on the road.

Sorry for the confusion. Generator head mfgd. by Marathon Electric. No affiliation with Marathon Coach whatsoever. Just coincidentally same name. Marathon Electric is pretty well known for quality components unless things have changed. Likely why PowerTech used their equipment.
The problem with mine was the end bearing had worn and allowed the rotor? to slightly wallow out keyway. There was a rumble under load that I hadn’t noticed but was obvious when generator was loaded. That was the rotor just barely touching the windings. Apparently not too far from shorting out – and whatever that might entail. This one has about 2400 hrs on it. Jeff said was likely caused by heavy loads hitting all at once over time. CruisAirs were hard-starts, sometimes requiring multiple attempts. I replaced both start and run capacitors in each (all were original dated 95/96). All start immediately now.
This is our first RV of any type whatsoever, so with some things like fuel mileage – I have no historical data to compare to. Same with this generator. Still looks new, nothing sounded especially odd to me.
