Derek and Dennis - thanks for your replies. Indeed, the Odessey is bigger than other models and, perhaps, the reason for not-so-hot gas mileage. It feels very big to me! Sure was a white knuckle driving experience in a rain storm (I'm still getting used to the height and the feeling of going around curves).
Dennis, thanks for your tips on overdrive; that should help. And, I'm going to get the vent covers because moisture sure was a problem on the maiden voyage. So, thanks for that suggestion. I'm fixing to take her out again and will also properly inflate the tires before I head out which should also help with gas mileage.
When I was asking about tips for the "home" part, I meant tips for the living space of the rig. For example, I can't figure out how to get the water heater started. Will go the dealer and have them show me when I have a moment but if you have suggestions, thanks for them.
I live in Western Washington and will be taking "the Beast" (affectionately called) on a 3 or so month road trip, around the perimeter of the U.S., starting in early Feb so any tips on long distance living are also appreciated.
Dennis, why is your rig named "Mrs Clark?" (very amusing how we name these and presume they are girls which, of course, they are).
