I came upon this posting quite late - been away. We had a similar problem on a Class A we had one time. The Service Manager at an RV Dealership in Colorado told us to use a Silicone Spray on the shaft which extends. I mentioned I only had WD 40 at the time and the manager stressed (in his opinion) the superiority of Silicone Spray over WD 40. Anyone know anything about the difference in the chemical makeup of these two products which might explain the manager's strong opinion?
I remember reading someone's very similar comment years ago in one of the trade magazines. The author said he listened quietly for awhile to an individual "stress out" about where do I store everything, and then he replied with just two words. "Define everything!"
