The OP is not asking what his Tundra can tow... Geez people, give it a break..
He wants to know how to keep a trailer all watered up in the winter..
As said, just plugging in won't do a darn thing unless you keep some sort of electric heater going. And that would have to be 24/7 or as long as you have water in the lines and it's below freezing temps.
If you must keep it 'wet' during the winter, than you have no choice but to keep it heated, so that's gonna be a chore right there. I know I wouldn't do that.. Even for my Dad! Love you Dad.. But, we have a house too..
🙂You will also have to keep the hose going to the trailer from the house from freezing too.. Good luck with that!
I keep my trailer able to live in during freezing weather.. Catch is, there is NO WATER in the trailer... I'll plug it in and it'll have lights and electric heat, but NO WATER. If you want to pee in the toilet, that's fine, but when you flush, there won't be any WATER.
I don't care what goes into the holding tank because it won't fill up and whatever is in there might freeze, but no big deal because it's not full.
Anyway, lets not make this a "what are you towing it with" thread when the OP didn't even ask about that.
