Technical Support / Re: Broke the Rear Exterior Ladder

« Last post by David T. Richelderfer on June 01, 2026, 03:10:42 AM »

Perhaps a phone call to Beaver Coach Sales & Service (BCS) in Bend, Oregon could get your questions answered.  BCS may have a new or used ladder.  Other than BCS, you might call on a salvage yard near you where old motorhomes go to rest; they are everywhere in the USA and probably Canada.

Technical Support / Broke the Rear Exterior Ladder

« Last post by Roger Milne on June 01, 2026, 01:33:00 AM »

Trying to back the RV into its new home and I miscalculated the height of the handrail on the exterior ladder. Is this an generic ladder assembly I can get somewhere or do I have to try and source a OEM replacement?

Thanks

I have been quite happy with my Continental HSR2 SA Tires in the 275/70R /22.5 tires.  I just put on my second set as the first aged out, but still looked new.  They are a load range J, so higher than most in that size, and they ride and wear good in my opinion but have a higher weight rating than any others that I have identified.

Before you purchase new tires, now would be a great opportunity to measure the weight on each front tire and each set of rear duals.  Ideally, the coach should be at "travel weight", i.e., full of fuel, water, and tools, baggage, clothes, food, etc.  Now check each coach's tire position weight against the maximum recommended carrying weight at maximum air pressure for the tires you have and/or plan to purchase.

When I noticed the front tires on our coach were showing radial sidewall cracking, I went through the above process and ended up switching our front tires from 295-95R22.5s to 315-95R22.5s.  Our front end weighed just over 8,000 lbs. on each side.  The tires on the coach had been 295s with maximum recommended carrying weight of only 8,250 lbs. or so.  The 315s at full pressure will carry about 9,000 lbs.

Yes, I had to try on the 315s to make sure they would fit not only with the air bags deflated, but also fully inflated... and check clearance with full left and right turning with deflated and fully inflated air bags.

Our coach has one Bridgestone 295, five Toyo 295s, and two Pirelli 315s.  The Bridgestone was to replace a sidewall damaged Toyo.  The Pirellis were pricey but that's all I could get at that moment!

Today, we adjust the 315 front tires to 125 PSI cold, the 295 duals to 115 PSI cold, and the 295 tags to 110 PSI cold.  We watch the ambient temperatures and feet ASL while traveling, and are prepared to add pressure if the temperatures get cold.  We also have 12 Tire Pressure Monitoring System units for the coach-8 and toad-4 (or tow'd) reporting in series continuously to a Silverleaf System dash screen.

Hi Jennifer,
Following is based on my experience over 19 years of Beaver (3 coaches) experience. All were kept garaged when not in use. First avoid Goodyear tires. I had heard about sidewall failures with Goodyear truck tires but had no issues with the set that was on the coach when we purchased it. Our second coach had Michelins which performed flawlessly and gave us a very good ride. Our 3rd coach came with Goodyears. At just over 5 years the front right tire sidewall exploded and threw the coach into a guardrail. Luckily no one was injured except our ins co which was hit for $65K in repairs. I had a tire monitoring system that showed no issues at the time of the incident. We were on a smooth interstate driving at 65mph and with no obstructions in our path at that time.  We replaced them with Toyos and they provided excellent performance up to the time we sold the coach.
IMHO Michelins give excellent performance and ride quality but are pricy. Toyos provide excellent performance but are sidewalls are a bit stiffer resulting in a slightly harsher, but not objectional ride. Others here have also noted the Hankook provides good performance and ride. Regardless of which brand you choose, replace them at 5 years.
Hope this helps. Steve

We have a 2002 Beaver Patriot Ticonderoga 37' and are in need of front steer replacement tires. We purchased it 3 years ago and have been slowly going through all the gremlins. What are the reccomendations from others that have done a tire replacement with history of success.After researching it has become a jumble of older posts. Our tire size right now is 275 70 r22.5
Any help would be much appreciated. Owners excited to make some much needed changes

Technical Support / Re: No Air Pressure??

« Last post by Roger Milne on May 26, 2026, 03:46:33 PM »

So I figured I’d close this thread out by telling you what the end result was. While the source of the leak was at the air dryer it turns out it was the turbo cut off valve that had fractured inside and was failed in the open position. A quick search found a replacement kit from Napa for $60 and 15 minutes of work the kit was replaced and air leak fixed, problem solved. I appreciate everybody’s help in trying to diagnose the problem.

Technical Support / Where do I find the MIOM?

« Last post by Lyle McIntyre on May 25, 2026, 09:02:43 PM »

I am embarrassed to post this, but I am have been unable to find the HWH MIOM.  I am tracing an issue with the motorhome continually dropping out of travel mode.  I have the HWH 700 series service manual for my coach.  I am trying to verify communications.  The manual directs to verify communications lights on the MIOM.  Based on what I read, I am looking for a potted circuit board with a 32 or 35 pin connector on one end, a series of LED lights on one side  and a lot of connectors on the other side.  Does this sound right for this system?I assumed they would be in the HWH box in the electrical bay (forward drivers side).  I do not see the two MIOM as part of that assembly. 
After searching I was directed to a variety of locations: 
- Mounted directly on top of the six pack.  It is not there. 
- Mounted in the bays near the six packs.  Possibly, but I have yet to find them. 
- Mounted in the frame rails. Could be, but I have not found them. 
- Mounted forward in the electrial bay.  Again,  I cannot find anything that looks like what was described.

I feel that I am being lead down the wrong path.  Can anyone point me in the right direction?

Thanks for the advice Eric.   I was very skeptical that the penetrating oil would work its way through the permatex,  but I sprayed the fittings down and then put the motorhome in storage for a week while I was too busy to work on it.   I went after those stubborn fittings a week later and every one of them came loose without resorting to the torch. They were not happy about coming out, but they did turn. Guess I owe the nice people at WD-40 an apology for doubting their product in that application.  That takes care of 5 annoying air leaks.  Only 67 more to go.
