Grease wheel bearings yearly - Really???
TT and 5th wheel forums are filled with advice affirming the need to grease wheel bearings. But, since Class A's are a whole different breed, and since greasing the wheel bearings looks to be $250-$500, and since this is not a DIY project, and since it's supposed to be done yearly according to the generic MH owner's manual, it seems odd that the manufacturer would expect to owners to regularly spend this much on one maintenance item. So, why would FR stipulate yearly re-greasing? If it's that critical (which it is) why re-grease the old ones? Shouldn't they have said "replace" bearings yearly? Thoughts?
PS - if I'm going to pay this much, what else should I pay to have done to the chassis?
