Bob, I spend a lot of time on both the Tiffin (even though we no longer own our Tiffin coach) and this forum. I really like them both, and pretty much for the same reasons. Both are frequented by people of like mind and who will go out of their way to help you with a problem, or give you the benefit of their experience. Difference here is, and you've already alluded to it, a much broader experience base.
You own a great coach, this will be just another great resource to help you get the most out of it.
Happy trails, and...
