Title: Porpoising and Norcold Replacement
Post by: Dennis Crawford on October 26, 2012, 12:43:27 AM

Folks,

I have a 2005 Monterey Huntington IV.  I seem to have a lot of "porpoising" or bouncing in the front end when going over imperfections in the road.  Particularly on bridges.  Has anyone this problem and had it resolved.

I am also having a problem with my 4 door Norcold when on gas.  The flame is not burning consistently.  It pops almost like it is not getting enough gas.  Propane tank is full.  Any help on this would be appreciate.

And finally, has anyone replaced the 4 door Norcold in a 2005 Monterey with a residential model?  Will the norcold go out the door and will a Samsung go in the door.

Thanks

Dennis,
I had a similar problem with flame not burning consistently. Cleaning out the combustion chamber/burner using canned air solved it for me. As to porpoising, your front shocks may be at fault. OEM installed "lifetime" Bilsteins will go bad. If you are getting any indication of cupping on front tires, it would also indicate shocks are at fault.

In our Thunder, we had a lot of porpoising until we changed the front and tag shocks to Koni shocks.  After that, the porpoising was reduced to only an up and down.

I know that some of our members have had to add weight to the front of the coach to correct the porpoising issue let see how the thread works out on the weight issue you may have this problem.

Koni shocks solved my problem. The factory shocks are good for @ 20-30,000 miles on most coaches. The Konis are a better shock, I now have 65,000 miles on  mine and they still seem new!!! Henry

As a plug for Koni shocks, my 94' has over 120k miles with original equipment Koni's and they still work great. I had them adjusted for a firmer ride when I bought the unit.

Jerry,
The only Beaver coaches that I know of who have reported a benefit from adding weight to the front of the coach are the short (30 to 33 foot) 4 air bag coaches like the early Montereys. On the longer 8 or 10 air bag coaches, adding weight to the front of your coach just increases your fuel consumption.

Thanks Gerald,

I didn't know all the details, but was with a couple of folks this summer that had had the porpoising issue.  They had both added the weight to correct the problem.  I don't recall the size of the rigs.  I was not sure of the size of the Huntington, so I just thought I would mention this issue.

One of the first items replaced when I got this coach new was to replace the shocks with Koni's.  Great improvement.
I removed the large driver side window on my Laguna IV to swap refrigerators.  It was a two person job, but not difficult.

I had my Beaver Bilstiens replaced just recently at BCS and my coach only had around 11,000 miles and I was bouncing all the time on bumps, bridges etc.  NOT ANYMORE.  Great ride NOW.  Get em........
