Hello ! Glad to hear about your new RV!! How often do you camp? We love pictures here. If you haven't started with any maintenance checks, I would start with those bearings. For the first time I would do a complete visual inspection (remove, clean, inspect, and repack). It will require the inner seal replacement. after that most bearings will just need a little shot of grease now and then. You can inspect those brake linings also while your doing the bearings. Remember no mods without pictures. Just ask any question were bound to give you some great advise. Welcome and "Stay Thirsty"...
