Hi Ben,
Welcome to the forums! Yup you have a "Classic"
Make sure to post up some pictures for us to enjoy!
Here is a link to the
owner's manual and the
addendum.
I think you are going to find that it is pretty light on information on how things work. What you will need to do is make a list of all your appliances; manufacturer, model number and possibly the serial number. Then hit up their websites for manuals for the specific items.
Good luck! and enjoy your new to you RV!
