We have a 2007 Select suite 31RL3, its new to us, previous owner had minimal miles on it, original owner had enclosed storage with moderate miles, from what Ive seen, it appears as a very low mile unit since the Dexter axle tags from the assembly line order are still hanging on the axles and very easy to read!!
Question, if this unit has spent a majority of its 12 years sitting are the sealed bearings still considered usable, or should they be replaced, have put a couple hundred miles on them towing the unit to new home but want some confidence with a long haul run this winter.
appreciate any past experience and input.
thx
