Winter Storage of Diesel in my tank

I would like to see where these three questions take us.
Do you use an additive to stabilize the fuel?
Full tank or near empty?
How do you keep the DEF from freezing in the tank?

I keep the tank full to reduce condensation. I don't use DEF, but have read that it starts to crystalize at 12 degrees F. The tank is designed to handle the 7% expansion on freezing. When running, the system is heated to keep DEF liquid. Starting and running with DEF frozen will not harm any systems and will quickly kick in when melted. No additives are available to prevent freezing while stopped, they would harm the effectiveness of the DEF to reduce emissions if added. This info is from Cummins:

Can't help with the DEF, but fill it and add a stabilizer and don't forget a biocide. The biocide will keep stuff from growing in the tank. The biocide can be found at a marine store.

I keep the tank as full as possible and use a biocide (we live in a warm, humid climate, i.e. Florida) whenever the coach is not in regular use (which usually means January-April).

I use stabil diesel, fill the tank, and live in the north.
Make sure you drive around for half an hour, with the genny running and under load, to get the stabil thru the whole system.

And then put her to bed and let her lay. Nothing to be gained by starting the main or genny engines during winter sleep time.

Treat your batteries good tho. If you cannot leave the rig plugged in all winter, pull the batteries, take em to a warm place, and hook up a trickle charger.

Fill the tank as full of fuel as possible. No additives added. Charge batteries with my battery charger once a month. Do not use the onboard charging system. Store mh in northern Iowa in an unheated shed. No problems to this point.....knock on wood....

Using something like Startron will prevent growth of algae and fungus in the fuel tank. I would be sure to only put straight diesel in the tank and not biodiesel in any concentration for many reasons.
