Hi Dale, welcome to the forum. A couple of things that may be of help to you. If you're not a member of FMCA (Family Motor Coach Association), join. Once you're a member of or if you're already a member of FMCA, join the Freightliner Chassis Owner's Club (FCOC)
freightliner. The have a section on their website about chassis maintenance. Join the CAT rv cluyb
CAT RV Club, an FMCA Chapter. Both of these are chapters of FMCA so you must be a member of FMCA to join either one. Make arraingnments to attend Camp Freightliner
Camp Freightliner at the Freightliner Service Center in Gaffney, SC., while in route on one of your trips to Florida. It's a two day school to familarize you with your particular chassis and how to properly maintain it. Schedule your coach for its' annual service while your taking the class. You can park for free (neither the school nor the annual maintenance is free) in their lot with 50 amp electric. There is a convenient sewer dump station w/water where you can dump your tanks and/or fill you tank is necessary. I attended the school several years ago. I still get my coach serviced in Gaffney every year.
Look into becoming a member of the Tiffin Owner's Net
http://tiffinrvnetwork.com/forum/index.php in addition looking at the Tiffin Owner's Forum section of this site. Like here it's free and there are quite a few on that site that can answer many of your questions.
