We had an RBW hitch that we bought in 1993 when we bought our first fifth wheel. We used that hitch through 3 fifth wheels (all of comparable weight and within weight ratings) until 2018 when we switched to an Anderson Ultimate.
Like others said, routine inspection and lubrication go a long way to prolonging the life of a good hitch. There was actually nothing wrong with the RBW when we replaced it. It just took two men and a boy (slight exaggeration)whenever we need to remove it so we had full use of the bed. We have been very pleased with the Anderson and have over 10,000 miles on it so far.
