There is a section in there called Sunline Owners Manuals. Right now there are 2 manuals in there from a 2003 and a 2005 Sunline. These are scans from fellow forum members. They give generic information about a Sunline camper and have some use full information that still applies to your camper. That files section also has a copy of the sales brochure for your camper compliments from our very own Sunline Fan.
A Sunline manual when the coach was bought new included one of those generic manuals current with the times and it had cut sheets for the appliances, like the fridge, stove, hot water heater that where actually from those appliance companies.
If you go to your appliance of choice, say a fridge, find the make and model. They you can search the web for a manual on that appliance. Here is one such site that has many appliance manuals http://www.bryantrv.com/ Look to the left and they have owners manuals and service manuals for certain brand appliances. If you cannot find your make/model there you can still get most of them on line from the manufactures web sites. The older campers get a little more complex sometimes as the appliances are not as readily available.
If your strike out and cannot a certain appliance or device let us know and we may be able to help. This digging gets easier once you have done it before.
Hope this helps, happy camping in your new coach and again welcome.
