We had this same problem when our coach was only about 1½ years old, our 2008 BH 3055RL only had a 40 amp breaker to operate the slides. Took it back to our dealer and they suggested installing an additional 40 amp breaker in parallel using #6 wire. It has worked fine ever since. I seem to remember there being a recall put out by Lippert on coaches like ours that only had the 40 amp breaker their remedy was to install a larger breaker. I'm not for sure but I think I read this on RV.Net and not here on our Forum.
