The fresh water tank drain line is in the rear of the unit about midway and about three/four foot from the rear end of the unit. It should have a cap on it but some of the new ones have a turn-handle valve on it. The low point drains for the hot and cold water lines are the blue and red hoses with the handles on them in the convenient center. I myself blow my lines out using an air compressor with about 40 lb of air pressure on the line. I have an adaptor that connects to the city water connection that can be bought at most RV dealerships or CW. I close the water heater bypass valve and proceed to clear the lines with air. I open one faucet at a time starting with the closest faucet to the line and working my way back to the faucet the most distance from the connection. I do this with both the hot and cold faucets, shower, and toilet. I also do this with the washer faucet but connect a hose to it and run any water into a 5 gallon bucket. Don't forget to purge your outside shower also. The back flush for the black tank I just move the air hose connection to that connection and let it run a couple of minutes to clear any water that might be in it and I do the same with the fresh water tank connection. The final step is to open the low point drains and drain any possible water that may have settled there. I then go and put a quart or so of the pink stuff down each drain and down into the toilet into the black tank and then put about a cup or so of pink stuff in the toilet to keep the gasket soft. That's it and have not had a problem so far with any freezing. I have a water softener and filter coming into the unit and I take it out, recharge the softener about three times for the winter layover and remove any water from the filter unit and take both inside the house so they do not freeze. Didn't do that the first year and lost the whole house water filter do to the water freezing in it! Lesson learned!
I don't remove the batteries because our Monte is stored in an insulated building and is plugged in 24/7 and I check it on a monthly basis for any possibility of the cells going dry but that has not happened either.
