winterizing after MH has been sitting

I haven't posted in awhile so if this is in the wrong place, please let me know.

My MH was winterized 2 years ago. Should I repeat the process or is the antifreeze that's in the line still ok?

Thank you.

  • Thank you all. I did have the gas drained and put in new. I had put in Stab-bil but didn't want to take any chances.

    I will add to drains and toilet then. If time, I will redo. I'do feel better.

    a previous motorhome sat for nearly 3-years due to family problems. it had been winterized and re-do it apart from adding some to the sink p-traps and to the toilet to keep the seal moist. I was worried about the fuel even though I had added Sta-Bil to the tank so i took it for a long drive once or twice during this period of inactivity to burn off some of that stale gas which was then replaced with fresh gas and Sta-Bil. when we were finally able to use the MH again we found the plumbing (as well as everything else) to be in good shape.
  • I,d be worry more about the fuel system, not good to sit that long. and if it was my rv I,d do it all over again. things dry out.
  • At a minimum I would pour some antifreeze into the drains. If they dry out that could lead to odor problems.
