Suspension · at 32,524 miles · reported Mar 18, 2011

Found both rear trailing arms to be cracked upon inspection. Replaced both arms to correct problem. Old arms were cracked to a point where total failure was eminent.

Engine and Engine Cooling · at 14,654 miles · reported Nov 6, 2007

With only 14,000 miles on vehicle the aluminum radiator began leaking where the core is attached to the tank. Manufacture has since replaced aluminum with steel radiators but would not agree to pay for any of the replacement since the warranty time has expired. I have talked to other people with the same type of motor home that are having leaks also. I feel this is a trend and maybe should be investigated for installing faulty radiators in these units. Radiators should last longer than 14,000 miles.
