If you are a first timer, taking care of the plumbing even with a list of steps and some video backup is not as easy as it sounds. First time I did it, I left the low point drains open and wasted a whole bottle of antifreeze! Then I could not figure out how to close them as I had forgotten how I opened them--that is they only close in one direction but opening is at a 90 degree angle. This year it went very smoothly so it was just a beginners learning curve.
We have a hot water heater bypass which took me awhile to figure out. I remove the plug on our water heater to drain it. First I closed the bypass valve which is under our stove next to the water heater. Then I make sure the water pump is turned off, open the faucets and open the low point drains. Our low point drains are under the shower, kind of a pain to access.
The suction for ours is next to our water tank. There is a valve that opens the suction hose. Have to have the pump running and the low point drains closed for the suction. When everything is correctly done on ours, it only takes a half bottle of antifreeze to get all the open faucets to run pink stuff. I close them as they start to run pink so that the antifreeze is forced into the other faucets. When that is done, I put a bit of extra pink in the drain traps, and in the toilet.
We also bought a winter cover for ours. Turns out that ours doesn't leak in rain but we did get a leak in the snow and ice. Especially when it was heated inside because I didn't winterize in time. So the cover is an extra layer of protection. I bought ours on Amazon as that is where I found the best price. It is a tent type nylon material that is longer lasting that the tyvec type material. Just put it on this weekend!
I didn't put in Sta-bil but now that I have been reminded I probably will. We try to run the generator every month or so but we are not that great at getting out there to do it.
Just about everything we do to the RV is rewarding for some reason. Guess we just really like the thing.
