I was so glad to see a 25.2 owner! We purchased a 2018 and I am sure you can help me. All THOR does is send me schematics or the water system…..which I already have. How do the silly low point drains drain! There are no valves, no plugs…and the lpd are off of the kitchen faucet only…so how to you drain the sofa side!! Could you give me a step by step list of how you winterize your coach? Thank you in advance.
