Winterizing question

[micron]

Due to Covid we never got the trailer out this season. Sadly my wife has anxiety issues.
Anyway I never de-winterized from last season. I think I already know but figured I’d seek opinions anyway.
My question is should I flush everything out & re-winterize or just leave it be and add a little to the p-traps & toilet?

If you used the cheaper pink RV antifreeze that contains alcohol I would replace it with no alcohol RV antifreeze.
I would recommend you at least blow out the lines and add some pink RV antifreeze to the traps. That would take care of any condensation you missed the first time. If you have RV valve lubricant than I would also lube the toilet seal and dump valves.

I'd leave it alone. I can't comment on the stuff with alcohol in it, as I always use the propylene glycol pink stuff.

Tanks got drained, the pink stuff displaced the water in the lines, and I consider that condition to be static. New water would have to magically appear in the system for me to want to re-winterize it.

Generally speaking you should be good. I might check the p trap and toilet to ensure there is antifreeze still in them. If not a quick splash, I like to float a couple drops of mineral oil to keep it from evaporating. Use only mineral oil not vegetable oil, or you will have a gooey mess. Oil is optional. I would check the battery fluid levels and the tire pressure. What is sealed in the pipes should be good.

Best winter cover for my 2020 Seneca

My 2020 Seneca is being winterized right now and we’re going to store it in my driveway. I live in Colorado, so we get snow, sun, wind, hail, you name it, we get it.
Looking for feedback on the best winter covers. Lots of covers out there, but don’t see too many for Super C’s, and a ton of mixed reviews.
