Another vote for Josams. If you decide to go there, call Barry Hamton with your axle numbers from the tag and any numbers you can get from Monaco by a phone call for replacement parts for your brakes, etc. The last time I talked with Barry he said that he could track down the info but it would take a little longer and possibly cause a delay in getting necessary parts. When I was there, they determined everything was ok and I didn't need brakes, etc. However, I did have them repack the wheel bearings while they had everything off. Excellent service and knowledge base.
