We purchased our present MH, a pre-owned 2007 Diplomat, last July,2011, and we are planning on replacing all the
tires this April 2012. They are not cheap by any means, but the peace of mind of having new tires under you for our future travels is just one less item to be concerned about. The tires will be six years old mid 2012, with about 32,000 miles on them.
As we have no maintenance service records, we also will have a total engine, trans, & generator service also this spring...2012. Then we will know what was done and when.........
