Richard, I believe your comment is the only one current, but might suggest a 45 galloon auxiliary tank that lays flat in the front of your bed? We have used ours now on its third truck and I consider it indispensable for travel. It installs in about one hour, two hours if it is your first install, and only has one moving part, a petcock valve. PM me if you're interested in more info. And you need to know that you can log onto
http://www.keystoneforums.com with the same credentials you use here (same site owner) where you will find many, many more members, and much more info on your particular RV. This site is populated more with Mobile Suites owners, and there aren't many members here.
