Tiffin Phaeton Aqua Hot -- 400D good enough?

Thanks for all the feedback. I know trailers pretty well...but motorhomes, while they share many systems, are a different beast altogether. The Aqua Hot may be one of those instances where I won't miss what I don't know. Heard many folks say they wouldn't own a coach after having a hydronic system. I've never used one...and yet with my 10gallon water heater in my fiver, I have never run out of hot water despite long back-to-back showers from three girls. I think the all-electric is pretty groovy, though. :) And I understand multi-zone from the hydronic systems is a very nice way to heat a coach. The Phaeton with Aqua Hot and heated flooring might be nice in the winter months. We have typically winterized our fiver...and said goodbye to it sometime in November...and hello sometime in late March. Hoping the motorhome will have us camping all year long. But...while I do have covered storage (storage facility with bays that provide roof, side walls, and back wall and open in the front), it isn't heated...so I'd have to re-winterize after each winter trip...and have read that winterizing with a hydronic system takes longer...and I can't used compressed air like I do now with my fiver. Looks like I have some more reading to do.
