I had a Roadmaster Sterling on previous MH & Toad.
Switched to Blue Ox when we changed MH & toad as it came with the BO.
When I closely inspected the BO and contacted them they would not recommend rebuilding with new parts and simply said buy a new one which I did as I was already committed to it with the toad.
I have to say I never had any real problems with either (since replacing the BO) but if I did it again I would go with a Sterling and the removable tab mounts.
Follow mfg recommendations for cleaning & lubing and you should be fine... theybare different and should not be treated the same no matter what internet posters recommend... follow mfg recommendations.
