Update on front axel weight issue
I'm sorry it's taken so long to give the end results for the issue that I have with the Berkshire MH. The issue started soon after we bought our 2011390RB Berkshire in may of 2012.WE found we where over weight on the Front axel and wasn't sure what to do about it. Sorry I couldn't reply to the original thread as its to old.I was asking about replacing the front axel.
I just got back from Gaffney SC after having the front axel updated and the tires replaced. The fix to this was that the front axel that Freightliner uses on all the XCR chassis under 12500 lbs front axel are the same casting. The brakes and air bags and other items make the difference as to what rating it receives. In my case to go from a 10500 lb axel to a 12000 lb axel was simply to change the air bags to a larger size. I found this hard to believe but was assured by ever expert that I could contact that this was true. Freight liner in Gaffney SC made the fix and did a fantastic job. I would say that is about the most professional shop I have had the pleasure of dealing with. They had the engineers from the factory do all the plans on the change and signed off on a newly rated front axel. They also installed new Michelin XZE2 275/80r22.5 tires replacing the 255's with Forest River picking up the bill for everything including fuel round trip. Forest River has been great once the issue was identified and I can't say enough good things about the end results.
The drive home around 840 miles was like driving a completely different MH. The ride and handling was solid and smooth. The speedometer and odometer are dead on according to my GPS.
This is about as good a outcome as I could have hoped for. I know that it still is a little closer on GVW than I would like but it is now very capable to carry the load that I had extended when I bought the MH and that makes me very happy.
I am also amazed at how it handled the mountains around Knoxville and Asheville. I know these aren't the biggest I will find but the 6.7 Cummins handled very well. I have had a lot of people say the ISB can't handle a 33000 lb. GCVW but it made it up every hill I came to and although I didn't win the race to the top I didn't drop below 45 on any of the grades. I got some good pointers on driving and getting the most out of the 2500 Allison and the 6.7 Cummins from taking Camp Freightliner. Mike Cody does a good job with that class. It's a fun two days and if you have the time and have a Freightliner Chassis I would highly recommend it.
Thanks to Mr D and Steve Levin and everyone else for the advice in getting this resolved. Also Forest River is a company that stands behind their product.
