Thanks. I was able to find out about the "6 gal suburban" from an old brochure, just not the gas/electric specs. I wrote PW earlier and their answer was limited (they said the 2012 used propane water heater; they did not mention trim level variations or options-so I've learned something here already!). I prefer to use only gasoline and electric. (Yes, I know about the Ranger RT designed for folks like me. This rig is local and just wanted to know how it compares in that aspect, with info verified beyond just dealer spiel. Guess I'll need to go down there and eyeball it again.) Thanks again.
