Good to hear you're feeling better, Dan.
We spent our first weekend this past weekend in our new 235S. The roller wheels seem to stay engaged with the flooring in the new model. I still get heartburn when I see the slide sorta pitch up at the end, but it stays in contact and sealed well. It was a rainy, windy, day and night. We were in Central/Southern NJ all weekend. No signs of leaks. I was glad I got the awning over the slide as an option.
My electrical problem is solved. A bad circuit breaker was stopping the shore line power from charging the house battery. My only currently known problem remaining is that the fresh water drain valve is leaking (the one used for winterizing). I corked the drain pipe and used duct tape to hold in while in motion. Bless duct tape!
I have mentally filed the fix you described for the slide. Love to hear what happens.
