Coach 410, 1996, has a single front SCS on the PS in front of the entry door and dual rear SCS on the DS behind the house battery compartment. I found that the hot discharge air exhausts out the bottom of the coach. The outlet is located forward of the intake air which is located under the bottom of the coach and aft of the hot air discharge. 

So, the cooler outside air is preheated by mixing of exhaust and ambient air. On very hot days, both A/C's struggle. Sometimes, the thermal on the compressor opens or the circulation fan stops.

Cresly at Newell said they used to build a diversion duct for the hot air discharge.
OK. 

To test, I have placed a divider between the intake and discharge openings on the bottom of the coach. Efficiency of the system, lack of compressor dropout and cooler inside temps seem to be realized.

I am currently fabricating a mud flap material, flexible diversion system between the two openings. Hot air should be pushed forward and cooler air sucked from a cooler location.
Because ground clearance is so minimal, I'll see if the diversion dams will make it over the terraces at the ranch, dips into RV parks and alligators on the freeway. If not, at least I had a wonderful experience learning to accept failure.

I’ll post photo's later.

Our current seats have only lap seat belts.  

We are considering replacing both chairs that have integrated shoulder/lap belts, and am looking for suggestions on where to purchase new chairs.  How difficult are the seats to replace (can I do this myself?).  Current drivers seat is an air ride, electric position seat and the co-pilot seat is manual position, recliner, non-air ride seat.   Also where is the best location to purchase new seats.  If needed we would like suggestions where we could have the seats installed if I can't replace them myself?  We will be at Newell at the end of October but the replacement cost from the factory is prohibitive.  So we are looking for other options.

Just ran across a great video of the Screamin' Jimmies. Enjoy and learn some interesting facts.

Some of you may already know about the lifetime warranty on your Fantastic Fan dome top. But for those of you who do not, just go to the Dometic web site, they own the Fantastic Fan line.  Call Dometic and they will replace for free, shipping included! 
I called them and told them one of mine shattered into pieces and the other has a crack in it, and they sent me 2 new ones!
Hope this helps you when you are in the need, as one day you will need it!

I was leaving the house this morning and had a new oddity pop up. In order to get out of my driveway I have to turn on the leveling system and raise my coach as high as it will go.  Once out on the street I turned off the leveling system and the chime stopped but a similar but quieter chime continued to until I reached 25 mph. All day since, as soon as i drop below 25 it starts and continues until I'm back up to 25.  Any Ideas?

This morning I left KOA Lafayette and started hearing a noise so I asked my wife to look outside the window and she told me the wheel was touching the sides, I stopped at a Pilot gas station and sure enough the coach didn’t lift to travel height (we could feel every bump on the road as well).

I went on the engine bay and there was some hissing noise coming out of there, were the valve actuators are and I thought that one of them was leaking air, also the pressure gauge read like 30 (honestly never saw the value when it was working before) I changed the coil from the valve and now I don’t hear the hissing noise but I can’t build pressure and the coach stays down.

The front wheels seem to be just fine.
Things I’ve tried:

Check if the solenoids have power some do, some don’t, not sure how that works (energized builds air?)

Tapped with a screwdriver in case some of them are stuck.

Looked at them really hard like I know what I’m doing! 

What else can I do?

There are four rubber mounts that mount the carriage to the coach that the Kohler genset rides on.  If these mounts degrade it will allow the whole assembly, including the genset, to slide out the front of the coach.

These are the mounts that Newell used:

The mount is a Lord 283P250.
It is in their catalog as a Plateform heavy duty vibration isolator.
Astrotex in Plano, TX carries the part. 972-424-8707. Price is $44 each x 4

I'm contemplating buying one of a couple of mid 80s coaches that have been sitting for a couple of years.
Basic and regular maintenance is said to have been preformed on both, as well as regular engine starting, but neither has been out on the road for a good while.
Besides the usual suspects (fluids, filters, belts, hoses, tires, and batteries)  what other chassis items might need attention after a long period of non-use?  Does/can  non use cause any of the components to degrade any faster than regular use? 
Knowing what to look for might eliminate at least a few surprises. I'm sure there will be plenty of those even with the best info and inspection.
Thanks for any insight.
