Jon, to answer your question, I started a new thread under Chassis.

Mark,

We upgraded from a quad Slide Dutch Star to a 2007 H3 Marathon double slide. We liked the Newmar but no looking back for use. Jeff pretty much mentioned everything I would have said.

Al, I do not know any enthusiasts, Prevost owners or otherwise that can track the evolution of the level low system. I know some changes but the reasoning behind them would only be speculation.

Very early conversions did not even use Norgren valves. When the Norgrens appeared might be mid to late 80’s. At that point the accessory system had to be maintained to hold at least 30 to 35 PSI otherwise the Norgren valves between the drive and tag axles would dump air and the rear would drop.

Just after the mid 90’s Prevost came out with a change that allowed air locked in the air bags when the coach was shut down regardless of accessory system pressure. At that point it was not necessary to maintain the 30/35 PSI accessory pressure. There was a retrofit that could be applied to older coaches so how a coach is set up today could vary from the production design.

With the introduction of the IFS came ping tanks at each air bag plus the ride height valves were changed from delayed acting to instant acting.

I believe at or slightly after that point in time the Norgrens controlling the front had some changes that I think eliminated the 5 port Norgren in place of one or two 3 port Norgrens.

I think I know this because my 3 coaches went through those design changes. I might be wrong. What I do know is my Liberty modifications make my suspension system and controls unlike other conversions so what might be true for most coaches may not be true for my coaches. For example, instead of one three port Norgren controlling the exhausting of air for all three suspensions is not true for my Liberty in which each has its own dedicated 3 port Norgren for that function.

Over the years these changes were introduced without fanfare so someone with a greater depth of knowledge on the changes, when they were introduced and the reasons for them will have to fill in the gaps or correct my errors above.

If this is confusing, welcome to my world.

Thank you Tom . As much as i try I just can’t seem to follow the path on the diagrams . I was able to isolate a air leak on the leans with the PDF but man if we could get the Video back that would make life much easier for us all . Thank s again .

I only had my coach for about 6 months and the same thing happened to my latch.A box of spare parts came with the coach and there was a door handle in there. I dug it out and it was broken the same as the one in the door. It was in Kenworth box and i can get a discount at Kenworth but at $ 2850 I decided to fix

Mine. So i fixed my old one so it will never break again. And it works great.

Larry,

Yes, Jeff updated mine to IPad and it works great. It’s a dedicated Ipad for Crestron and my Pressure Pro, I don’t use it for anything else.

Pay no attention to The Godfather Larry, everyone knows the rose pedal dispenser is on the outside of the rotting Liberty aluminum holding tank, so your Tecma smell inside would be the same as a Liberty with a Tecma.

I do not have any images of the original camera. It was a little bigger on the face than the new one but much longer. About a foot that extended up inside the coach fastened to a beefy steel bracket.

Mine is the RVS-770 which i have seen from multiple vendors with different names on them. The picture is crisp and clear both day and night. I would get that exterior lense off of there.

Geo,

In our neighborhood ( https://gardensrvvillage.com/ ) we are fortunate to have a professional person that has trained thousands of “better halves” to drive RVs.

Glen had driven our previous coach just enough to be able to get it to a safe place in case of an emergency. He is now progressing well in a multi-level formal training course. On our recent trip to Orange Beach, Glen drove twice and did extremely well, passing Rain 101, Rain 201, Construction 101, and Extended Bladder 101.

I see a huge advantage of me NOT being the actual trainer. I had to pass the trainer’s course of how to be a passenger. It was tough and I’m still in therapy.

That is a really nice looking coach. If I was upgrading, I’d go see it.
