Storing My Diesel Truck Over Winter Advice

I fill it up, throw in a can of seafoam and put it on a batteryminder plus maintainer. At least I feel like I have done what I can while its in storage.

I have a 2009 truck. (Duramax)

I bought it new.
It sits from October through April most years.
It hit 76k miles last weekend on my last camping trip of the year.

I haven't done anything special to it when putting it to bed for the winter hibernation.

I probably should have filled up the fuel tank every fall. The fuel gauge quit working after each fill up in the spring of 2021. Within 10 miles it would register correctly again.
Spring of 2022 it died completely.

I've read that corrosion on the sending unit is the most likely cause of the issue.

IT SURE IS! (see reply below)

Those of us in Washington get rusty brakes every time it rains. Do we go out and change out those rusty brakes? NO

My brakes get rusty in the summer when I wash the truck. I don't hcnage them out after that happens either

Not wintering over in a dry garage.

Where's the f**borg "like" button?

How is is "hard" on them?
There's no wear and tear as it's not being driven so your claim makes no sense whatsoever.

Letting "old" stuff sit for long periods of time can and does lead to seals drying out, old gas in chit that plugs up carburetors, etc.
But you're correct, that stuff is 99.9% inapplicable to the OP's scenario.
It's just old guy wives tales, told totally out of context.

Use Stabil in the fuel. DEF has a service life of about 6 months.

Letting vehicles sit for 6 months is hard on them. Pull the batteries and put a low voltage maintainer on them.

Aside from the last part about a maintainer, which would also not be necessary if they were disconnected fully charged (but not a bad idea), whether you "pull" them or not, the rest of this couldn't be more false or comical.
It's silly stuff like this that get people like the OP thinking they need to do a whole bunch of stuff to let their truck sit for the winter.

ZERO need for Stabil in diesel that is sitting for 6 months, it isn't even an algicide if that is a concern.
DEF has a much longer than 6mo shelf life unless you let it sit out in the sun with the lid off in Nevada in the summer...

And I can't think of a single other thing that would be "hard" on it, unless sitting for 6 months out in the sun in Nevada, or under a Walnut tree all summer or in a swamp.

Yes it was a real fighter, 21# on opening day.
