I've been attempting to winterize the trailer for the first time. I've drained the back grey & black water out from the back drain, ran the sinks, shower and toilet out, but cannot find a low point drain for the fresh water tank.
My classic has a drain petcock behind the passenger side front wheel. There are 2 low point drain petcocks for your plumbing also in the same area. Be sure and open your facets when draining the plumbing. Some water may find a low point so be sure in the plumbing so be sure you buy some RV safe antifreeze and circulate in your system as a final step. All drains and tanks should have a little antifreeze in them. Also there is a book that came with your unit they will explain the steps.
