Well, congratulations on your new rv. I'm sure you'll find anomalies that you'll need some info on. The dealers and brochures and paperwork really tell you a lot of nothing.
Anyway, if you have specific questions there is usually someone that's pretty versed in things that will be able to help you here. As far as other things go, I'm a firm believer in "if it ain't broke, don't fix it". Not sure I'd be doing a lot of upgrading things until you become very familiar with your new unit and know what you want to upgrade. Anyway, you asked, thats my 2 cents, which is worth about 1/2 of a cent nowdays. Good luck on the new home to!! Sounds exciting!
