Slowly getting my RV skirted. About knocked myself out yesterday with the spare tire hanger in the back.

I'm still figuring out what I want to use for skirting my trailer. I need to make a decision soon and start getting on that.
Yes, winter is fast approaching.
Yes. I still need to install my tank heaters, too. But I gotta pull the belly pan to do that... ðŸ˜
So far I don't had a reason to use them, I went through -25° F without freezing up, skirting worked good enough. I do have a Camco heated water line rated for -40° though.
That's good to know, but I figure that it can't hurt to have a couple of heaters on the tanks just in case.
Not being able to empty my gray or black tank is not fun. 😅
No it's not fun at all. I don't hold, I'm connected to sewer, just have to double or even triple flush toilet and run lots of water to get sewage downpipe.
I have a macerator pump and about to 75'of actual 3/4" hose. I can't connect directly to the sewer line. I have to store and then pump waste ~once a week.
