That made me laugh. Not sure why, cuz it’s true, but that was funny!

You guys need to be a little more clear if the mirror or the bracket is vibrating. If your assembley is vibrating there could be a couple other causes.

Maybe pumps are different (sureflo here) but I thought all had pressure tank. I know my old coach has one and we don’t experience a drop in pressure.

Jeff,
my biggest concern would be the weight raitings, especially for a vehicle like our coaches. I run 10 ply tires on my dodge 1500 truck. Overkill, but when I was pulling 12000 + pounds, I wanted the extra stability in the tires.
When I went looking for new tires for my coach, I was told they were backordered. This was in March. In July, supply was still really hard to come by in qty. I went with TOYO’s and have been happy. Got them mounted for something around $575 each. THat was the tires, mounting and paying the government for all their hardwork.
This was the price without any discount program and they had them in stock. The having them in stock was the deciding factor for me, as I needed them before leaving on a 4000 mile trip.
I know it’s still expensive, but the TOYO’s are a great tire and much cheaper then the Michelins. That and you can get them without hunting around the country.
Oh and the shop ended up giving me $400 back for the tires they took off for what they would be able to resell the used tires for.

Karl, I think FlyU is referring to Vail Lake RV Resort, southeast of LA about 75 miles. I did not mention it because I’ve never been there and don’t know anyone who has. I defer to FlyU about whether it is nice. It is near the Rancho California place I mentioned. The place north of LA that FlyU refers to is Valencia Travel Village, which I described.
If you will be travelling between SF and LA on the west side of the Sierras I recommend that you head for the mountains and plan overnights or longer so that you can visit Yosemite and Sequoia national parks. If you have the time, they are not to be missed. They are, however, a long way from the beaches and neither can accomodate a bus inside the park, but there are good campgrounds nearby.
Unfortunately, driving SF to LA along the ocean is not really possible in the bus. Highway 1 is length limited from San Simeon to Monterey through Big Sur. It’s a breathtaking drive, but must be done via toad. You can get your beach fix from around Pismo and south.

And this makes me even happier that we are doing all of the updates on ours. Hopefully with new electronics and fabrics the desire to buy another bus will peter out quickly as there isn’t much more I could want.

Will give it look thanks

It is pretty important for every one driving coaches to understand the pneumatic systems. We are all driving the equivalent of a large commercial vehicle and except for motorhome drivers, everybody else is required to have a license that proves they are qualified to drive one. Part of the requirements to obtain a license (a Class B) is an understanding of the pneumatic system. If you don’t understand the systems, and don’t know how to do a pre-trip inspection of the system you are not qualified to drive such vehicles. No state will issue a Class B license unless you demonstrate that understanding.
At the very least, and for your own safety learn the basics of our coach air systems. They may seem complex and daunting, but when you study how the systems work you will see how they work, how they are set up to keep you safe in the event of a failure, and how you can interpret what the pre-trip test is telling you.
One of the most important things to understand is that the pair of brake system gauges on the dash are only for the brake systems and have nothing to do with the suspensions or other air operated accessories including those installed by the converter. If you have a total catastrophic failure of the aux system, such as a failed air bag or defective valve your protection valves between the brake systems and the aux systems will maintain about 75 PSI in the braking systems which is more than adequate to maintain full braking functions.
If the brake system pressures are holding steady, and the aux pressure gauge (if the coach is equipped with one) is flickering as Jim describes it is not likely the system is losing pressure and being refilled. If I had to guess the problem I would look at the gauge first to see if it has a problem. Some coaches were equipped with electronic air pressure gauges and it was not uncommon to see them dance a little.
The typical coach has a 120 PSI compressor cut out, and 100 PSI cut in so a variation between 110 and 120 on an aux gauge is unlikely to be an indicator that the pump is cycling. Having said that, keep in mind converters modify the aux system by adding components and an aux compressor. If the system is in fact dropping pressure as indicated by the gauge, the aux compressor could be cycling on and off. A leak large enough to make the gauge fluctuate as described should be easy to detect.
FWIW, once a coach is leveled the automatic leveling system should be turned off. Wind and people walking around inside the coach create enough movement to cause the automatic system to constantly exercise to try to keep the coach level. Running an aux compressor every 30 minutes is a good indicator something is not right. In fact that is a big leak.

Tom, I have same one, 20K kohler with Yanmar, it did a very similar thing recently with all roof airs on and some other loads going, coach was low on fuel, but that wasnt it. Not sure what it was but it righted itself and has been fine for nearly 50 hours since.

I use the camco but I modified it with a 3″ elbow works great
-
now it has been removed, maybe it sold? Does anyone on here know.

I use one of those small turtle wax buffers(about 5 or 6 inches) to put the wax on and wipe it off by hand when Im at home .Its faster and the darn thing only cost about 20 bucks at walmart plus the small size works out good with the stainless and gets in places that the bigger ones wont fit. Im thinking of adding it to the on the road equipment, it weighs so little.

How did I know this discussion was going to take place?
Tom is right in that airing up the belts stops them from flopping around. If you are going to do as he suggests to get the benefit of air in the aux system wait about 15 seconds after turning the key on before you hit the starter. Air to the belts is blocked with a “key on” solenoid valve on some coaches and you need to give some time to get the valve open, and then for the air to fill the small belt tensioning bellows.

I take what was called “Hollywood” showers all the time, and never run out of hot water. Granted I shower after John who is military and takes maybe 5 minute showers. But seriously I’ve showered with the washing machine on and haven’t run out of hot water, and this with only our electric hot water heater on. Maybe you need to be first in line. 🙂

Jon is right.
I have manual “valves” to control defrost and recirculate functions. I also have a shutter on the spare tire compartment that Liberty installed to protect the Cruisaires while under way. This shutter can be manually overridden with a switch on the panel.
I also have the lever I have mentioned that opens a “valve” admitting outside air directly into the cockpit.
Besides all this Prevost provides an air cylinder operated outside air intake damper that admits outside air (and dust) into my OTR system as well.
Jerry, perhaps you have this outside air intake damper (located on the port side) and it is in the open position.
