Welcome to iRV2
(and hopefully you will allow me to add some "Monaco karma" to your name on the left also!)Congrats on your 'new to you' Vacationer.
As far as finding out if you have the "optional heating pad" .. I think your best bet is to call Monaco Tech Support and ask them if it does. Also have a "build sheet" emailed or sent to you. That sheet will give you all the info on your coach. (You will need your "coach number" when you call them.)
Again...welcome to the forums...we hope you visit & post often!
PS..can I add that "karma" now?
