Technical Support / Air bags and shocks for Roadmaster M series

« Last post by David E Iversen on July 09, 2026, 06:47:58 PM »

Hi All,  New guy here posting for the first time, go easy on me!  I just bought a 2004 Beaver Monterey (Coronado) about 4 months ago.  My wife and I did some significant remodeling.  Just got back from a trip and it definitely needs shocks and the air bags were noted to replace when I had service done at Premier RV.  I have 2 questions, does anyone know of a place in or near Boise ID to replace 8 bags and shocks, or does anyone have any comments good or bad as far as Source Engineering in Eugene to do the work?  Thought about doing it myself but I have no means to block up the coach safely.
Like I said in the intro I just returned from a trip in the coach.  On my return the first thing I saw was my toad covered in oil and the back of the coach dripping of oil.  It is at CAT right now.  It was found to have a cracked cylinder head at the back of the head where a plug caps of the high pressure rail on the oil system.  Any of you had that issue?  Wow, expensive fix!

Tom,

Your 2008 may be different,  but the HWH slide controller on our 2006 PT is mounted to the front firewall, passenger side . Slide the generator out, lookup on the firewall across from the headlight bucket. It takes a contortionist to work on it.

The forum Coach Assist contains manuals for HWH & PowerGear.

I thought Monaco went to PowerGear on  2007 & newer units.

I have taken the metal cover off the AC panel, and there is no access to the carma. I tried to send one picture, but it keeps saying to large.

Though our box is on the ceiling of the electrical bay, streetside foremost, your model coach may have it elsewhere. 

That said, individual slideout failures are commonly due to a faulty solenoid.  If I recall correctly, and thats a big if these days 😁 , the front curbside one on a four slide rig (electric bed slide but hydraulic genset) operates via the 4th pair, or one of the end pairs of solenoids in the pack/manifold.  The pack should be with the fluid tank under the entry steps next to the genset.  Solenoids that stick or with some sort of dirt occluding a seal won’t allow fluid flow.  Some say to replace them in pairs, others say single is okay, and some reclaim them with new seals.  When mine act up by popping out a closed slide an inch, simply cycling its switch out a second then back in is the fix;  it clears the seals apparently.  More information about the slide solenoids may be found searching herein for posts on that topic, using the Search tab in the above left menu line.

But if your slide isn’t operating at all, it could indeed be electrical instead.

I’d post pix, but for some reason the site won’t accept even my low res ones anymore 🫤 .

Bobby
As Steve was saying the earlier models used ACME A/C dash units .
In most fan control system there will be a dash mounted fan speed control switch and a blower resistor mounted in blower housing .
In the case of the early Beaver coaches how ever that resistor is divorced and mounted lower just below the driver's side frame rail behind the front cap on the fire wall.
The Blower resistor consists of three or four heavy wire wound elements and a thermal fuse which looks like a diode
I don't know why Beaver decided to mount the resistor where they did on these units but by doing so the resistor no longer has the benefit of the air flow it would have had if it where mounted in the blower housing.
To make a long story short if the thermal fuse is blown the blower speeds won't work.
In these earlier coaches the resistor was mounted in a perforated cage and was a Ford part used in a 1980 Ford F100 with A/C
If that is what your coach has the part number on it should read.   D8BH-19A706-AB

Here is a link with a picture for clarity.

I have a 2003 Patriot. I replaced the existing camera with a replacement and it did not improve the picture. I believe that the old connections had lived their life. I did not want wireless due to the the length signal would have to travel. I ended up going with this system. It is not easy to wire, but we'll worth the udgrade
 in quality.

Not sure if the 06 has the same system as the earlier beavers. If so check out the Acme AC diagram in the HVAC section of Coach Assist. There is a board with a series of relays on it that control the dash AC, dash fans, etc. Sorry but I don't remember its location.
