Help in choosing a tow bar

Yes we definitely want one that stays on the Motor home. We spoke with both Demco and Roadmaster, but I think Demco has a better warranty and they said the new Victory series don't have a lot of maintenance. Everything is sealed. I guess a lot will have to do with which base plate our dealer thinks we should use. Based on all my research Demco, Roadmaster and Blue Ox all have good and bad reviews and all seem to be about the same with ease of use. I guess we will let our pocket book tell us which one, plus I know the parts lady and she is going to offer us a deal. I would think she knows which ones sell the best.
