Contact Keystone and give them your VIN or build number and get them to either send you one or a link to a PDF.
This is an excerpt from another thread I posted earlier.....
I little different from Bob, but somewhere in a cabinet their is a "Build sheet" posted. Take a few pics and print it out. First, go down the sheet and make sure that you have the factory manual for each item from the item's manufacturer. If you don't have one they will be available online. Then assemble them in the manner that works best for you. Some punch holes and use three ring binders, and some use accordion files. Then take time to walk through the manuals. My thought process is start with the chassis manual and walk through everything with fuse box and breaker locations being a priority. Finding it in your driveway on a sunny afternoon beats a cold rainy Friday night on your way to camp. It's first because no matter how well everything works, you gotta get there first.
After that, go to the coach manual. Again, put your hands on everything and if you can't find it, come back and ask. As has been said, these manuals are somewhat generic as there may be upgraded items mentioned that you don't have and locations may be changed from one model to the next. Find your on board water filter, pump, transfer switch, house breakers, low point drains, water heater valves, TV amplifier switch, leveler switch and pump assembly, and anything else. Then go down the build list and do the same again. Make sure you find everything and flip switches and turn levers. This is also a good time to start your tool box as sometimes you may have a panel or three to remove and many of them have the square head screws.
While you are doing this, I suggest that you get a couple of rolls of painters tape and sharpies. Make notes and labels. If you see something that isn't right, you don't understand, or needs repair, put up tape where it is easily seen and start a "punch list". Some things may effect livability and are more of a priority and many will be cosmetic.
Bear in mind also that this was a discussion about a new Class A, so you can skip the chassis manual, but add one for the axles and brake system.
