I know I would. Sure, some buyers won't seem to notice or care. But I'd guess that majority of lookers will see that it does enhance the unit. When we sold our TT with new bearings, brakes, etc, it was this that sold the buyer on the unit. He was looking at other units in the same price range (about $10k) but ours was only one that had new brakes, bearings, newer tires. Other units the owners could not say, or didn't know, or would say "it does not need it" when in reality they didn't know.
Do it for peace of mind for your remaining trips and for knowing you did the right thing. You can then sell knowing you have a complete package for the new owner.
