You can get information about the way various members winterize their RV's by doing a forum search on this topic "winterization" or "winterizing". While there are some minor differences from model to model, the process is essentially the same.
I think Keystone has a video on winterization which you might check out by visiting this website:
www.keystonerv.com.
If you do a Google search on Winterizing an RV, you will find dozens of sites all of which outline the basic steps.
When you locate the pump, as long as you can get your hands and most of your arms in there to disconnect and connect hoses, you should be fine. You'll also have to find the HW bypass valve to your HW tank. You need to drain this tank and shut off the water supply to it so you don't pump 6 gallons or so of RV antifreeze into it.
