When I should winterize our TT?

You need to watch your night time temps. When you expect those temps to drop below freezing , its time to winterize.
Unless you are not planning to use your rig, then do it now and you won't have to worry about anything.

And it starts...

Good advice here.
I have been RVing for 25+ years and I still have the same question...
"When should I winterize?"
All I am sure about is that I don't need to winterize June-Aug. and that only is true for where I live. The rest of the year...????

Never, head south where it won't freeze.

Before winter sometime after fall.

Are you done using it for the year?

If yes, winterize now.
If no, you either take a risk or winterize between trips.

Personally, I prefer the head south option.

If you are not doing it yourself and going to a dealer, book something now to avoid the fall rush.

I am doing my this weekend sinceI know am done for the season due to upcoming travels with my job. Watch te night time temps, and if your done, then prep it.

Before you start having temperatures below freezing for long enough to freeze water in the lines.

That is something that depends on where the RV is stored, and whether the plumbing is exposed or protected.

Where I live, before the end of October. If I use the RV between October and April, I will dewinterize as I move to a warmer place, rewinterize before going back to cold storage. Actual dates would be different if I lived in Minnesota or Mississippi.

Some good advice from folks above. What you DON'T want to do....

What I did last year. Made my appointment during the last week in October for early November, a time when we were having daytime highs in the 70s, lows in the upper 40s/low 50s. Two days before the appointment, it was 74 degrees. But then...the temp fell below zero the night before I was to take it in, and was in single digits on my appointment day. They had to put the trailer inside to warm it up before they could do anything. And I was not alone.

Yeah...my bad. To paraphrase a current DirecTv commercial..."don't be THAT me"! :S :o
