After reading an article in the january, 2011 motorhome magazine, I discovered a crack in both trailing arms. Contacted holiday rambler/monaco and was advised they would not be responsible for replacement. In april, 2012 new trailing arms were ordered from source engineering and replaced at my expense.
Recently purchased 2006 holiday rambler motorhome. The issue is the rear trailing arms in the chassis. Monaco,llc who was & now is again the manufacturer of the holiday rambler put an undersized trailing arm on thousands of mh ranging from 2002-2009.
We were traveling north on highway 54 thru kingdom city mo. When we came to a stop light. Upon applying the brakes the vehicle listed violently side to side. I immediately pulled off on the shoulder of the road and inspected the vehicle but found nothing wrong.
