Question Hey Guys, I'm buying a 2006 Monaco Executive, Roadmaster Chassis Question?

I'm having the Rig inspected by
Redlands Truck & RV Performance Center

In Redlands CA.

Is there anything I should be aware of, or tell the inspector to look out for?

My wife and I are flying down after the inspection to purchase and drive back. While driving I know to listen for noises but is there any Model or Brand specific issues I should keep an ear out for?

Thanks for your help This is my first post here...

Oh, Specs.

525 ISX, Allison 4000, S- Series Chassis

Oh yea, the radiator. Somone said that if it's aluminum I might need to have it replaced... Is that true?

Redlands are good chassis people, air leaks are a big problem which they can fix.

I don't know how good they are with the house. I assume it has the computer and multiplex system. I would want an inspector that is very familiar with it to check the house. The Executive has lots of neat systems which should be thoroughly checked.

I think we saw your coach. It's a very nice low mileage coach and PCG is great to work with.
Hypoxia is correct about the air ride system. There are lots of solenoids and valves and over time they tend to develop leaks. After you shut down the engine and set the Auto level, see how long it takes for the system to leak down and the electric air pump has to turn on to resupply air pressure. It should last overnight.
Also make sure the auto leveling system is operating correctly.
Go through the Aladdin system very carefully and insure all the tank quantity systems work correctly. The black tank lower sensor tends to clog up. The only way to check this is to add water using the flush system and see if the sensor responds.
Check ALL of your batteries (coach and chassis) very carefully. They sometimes move the old engine/chassis batteries to the back of the coach battery drawer and then add new batteries only to the engine battery drawer.
Check the tire dates. I would not accept anything over 5 years.
Check all 3 AC/heat pumps for cold air individually. These are ducted systems and if all 3 are running, it's difficult to tell if one is weak. It will take 5 min for each one to come on after you set it to cool.

Look at the roof carefully. Look at the skylight for cracks. Look at the Girard retraction system and insure they are intact.

Look at all the slide out seals and insure they are in good shape.

Check the Aqua Hot on both AC and diesel.

Check the windshield wipers. They are often overlooked.

The ISX 525 is a very nice engine. It's smooth as silk and a good comprimise for fuel economy over the 600 or 650.

If it has Eaton Vorad Smart cruise, you will need to test drive it to insure it's working correctly. If someone pulls in front of you or directly on your right side you will hear the beep and see the led lights change to red. The cruise control should also slow down if someone is directly in front of you.

Check the engine brake on both high and low.

Do not trust an inpsectors report to mean everything is 100%. These coaches have several complicated systems and many inspectors are not familiar with large class A coaches and all the systems.

Be prepared to spend another $10-15k on all sorts of things after you purchase it.

If its over 40 feet, should have a class B. Now in CA I believe it will take a class B anything over 26000 lbs

Look at the bottom of the drivers side living room slide. If the edges front and back are torn up, you should have slide skis installed. Let me know and I can give you the information.

The 26000 pound limit doesn't apply to motorhomes. Only if you're over 40'.

Also look at the slide seals, especially the tops under the slide toppers. These tend to come loose and commonly need replacement. The Aladdin and the multiplex system need to be thoroughly checked out and can be a major source of problems.
