Aha! Rick, you touched on one of my many questions about the new Bambis. The Owners Manual (available on the new Airstream website) doesn't mention ducted heat to the tanks, and I think I was told by a salesman that in fact the Bambi doesn't have that feature.
If anyone can really check, I'd be curious to know. Otherwise, I would assume that heat leakage through the floor provides at least some warmth for the tanks (and hopefully, there is insulation surrounding the other sides of the tanks). Who wants to crawl around under their Bambi to check?
As to the generator issue, I was considering the eu1000 instead, only because I am going for lightest possible overall weight and have no interest in running satellite TV, air conditioning, etc. It would be just for re-charging the battery. I know that charging time is related to the electrical load in the unit at the time (e.g., the battery only gets the surplus power). If I got the eu1000 rather than eu2000, I am hoping the battery re-charge time would be the same if I wasn't loading the DC power with other appliances at the same time. But maybe this is wishful thinking ...
Rick and Rod, you both do the same kinds of trips my wife and I do! Rick, we've been to Anza-Borrego (3 times), Joshua Tree, Death Valley, Yosemite, and Big Basin -- and we live in
Vermont! Perhaps we should face reality and just move to California?

Or perhaps buy a Bambi in California and fly out to visit it once in a while!
