It's always nice to take a new out for the first time (and such a great weekend for it too). Glad to hear it was a total success.
I mirrored your experience in a lot of ways this weekend too: new 28RBS on its maiden voyage. Although I have two boys, and the dog would never forgive me if I left him behind. I found one minor problem with mine: the catch for the main door was screwed in about 1/4" too low, so if *any* (and I do mean any). pressure was put on the stabilizers, it lifted the door just enough to no longer line up with the catch (and not latch). Easy field fix, fortunately.
