Steve,
to the forum to both you and your parents. It does sound like they get the better end of the deal if they're using the trailer most often. I think we all have our "ups and downs" in RVing. When something isn't going as we planned, it gets "down" pretty fast, but after that's resolved, it's all "ups" again and smiles until the next one. Fortunately, for most of us, there's more good than bad and we all enjoy camping much more than we enjoy talking about it (hurry up spring)
We'd like to hear about some of your issues and how you fixed them, maybe we can exchange experiences and everyone learn from each other.
Pull up your keyboard and sit a spell, I'm sure you'll find lots of interesting things to ponder.
John
