I am a seasonal camper. I lubricate my gears 3x a season, when I open and close and once 1/2 thru the season. Our slides out 24-7, I also condition the seals the same 3 times and after the trailer gets a bath. I use the recommended products. No issues in the 3 years....(knocking on wood). My theory is that a little bit of time on maintenance now and then, will save me mountains of time and headaches later. besides that, when DW see's me working on the trailer, she goes in and makes cookies! I think she thinks, it keeps me from asking her to help...... Hmm in fact I think I have some maintenance to do this weekend.....
Happy Trails ya'll!
