We had the Big Foot Automatic system added by the factory when we purchased our 2011 Sunseeker 2650DS purchased from RV Direct in Albany NY, I believe it was a $2600.00 adder? Works great. I understand that you need to be careful when doing this manually not to twist the frame of the chassis?
I have been winterizing my class c by first blowing out the lines and then pumping RV anti-freeze into all the lines, traps, etc. I then pour about 1/2 gallon into the toilet. We had a cold snap where tempertures hit close to zero for a few nights and I noticed that the antifreeze in the toilet was almost frozen; went in to run the generator for 2 hours; it was more of a hard slush than solid. Hopefully it does not get to the point where it expands before truly freezing. Have not had any issues in the past 4 years. Any thoughts?
