Even though I just bought a 33' TT and pickup to tow it with, I still intend to use the B+ for short and/or "fast" trips for the forseeable future. After four and a half years of constant driving, My venerable B+ is getting somewhat long in the tooth with over 83K miles. I must admit that other than accomodating obvious issues for driveability, I have spent little on preventative work, and none on cosmetics. I am contemplating the following: 1. Resealing the slide to see if I can get it to stop leaking once and for all. 2. Recaulking the top - purely preventative. 3. Recarpet. 4. Reupholster the coach furniture (or replace the couch to make a wider bed and match the dinette material). Repair some of the drawer hardware. 5. Perform some maintenance on the chassis - brakes, serpentine belt, tune up. 6. Repair the TV antenna wiring (I had to replace the antenna after an unsuccessful attempt for it to climb a tree while the vehicle was in motion - the wiring is still not good). 7. Get some "bondo" work done on the plastic piece that holds the tail light - backed into a tree.
Once this is all done, I can figure another 50+K miles of reliable use before thinking about suspension parts. One of the joys of having an over capacity chassis is that the components are relatively understressed, so springs, bearings, CV joints, and other components will likely last a long time!
