I will take this opportunity to ask you fellow '98 Coachmen owners about this. I have only had this unit 3 months and no traveling yet. When I got it,it was very cold outside and I felt a slight front tire "washboard" feel and thought it had a tire flat spot from cold storage and not being run since last Oct. Haven't been out with it on a hwy until last week (on a newly paved hwy)and I still have that little tire bump..the tires are Kelly's M/S,year 2011, with only 2500 miles on them. Wondering if something is wrong with them such as a broken belt or is it the M/S tread..I had it all checked over when I bought it-mechanic said it's in great condition..only 41,000 mi. on her...Any ideas would be appreciated!
