Bleederguy --
in my Good Sam Club membership profile I changed my 2007 Damon Astoria to 2008 Astoria and Good Sam returned three safety recalls for the 2008 model (see attached PDF file).
Hopefully the previous owner left a large "bag" containing the Astoria owners manual plus lots of owners manuals for each item in your motorhome. On page 2 or 3 of the Astoria manual is an owner's registration form you can prepare and mail to Thor Motor Coach as soon as possible. If you don't have an owner's manual, it available from the Thor website -->

My wife and I purchased a 2007 Damon Astoria two years ago (upgraded from a 30 foot travel trailer). We have had several very enjoyable, most trouble free long weekend outings. I hope you are enjoying your Astoria.
