When I lived in “upstate NY” for 35 years, before I had the 6” cement floors poured in the non-heated garage, I place two layers of 6 mil polyethylene over the gravel bed.
Winter truck procedure:
Fill the gas tank with regular (regular ethanol formula) fuel before hibernation and put gas treatment in the fuel tank.
After filling the tank and treating the gas, I ran the engine for 15 minutes.
I left the truck-radial tires on the truck, and the truck/tires on the floor.
The 6v battery was left in the truck, on a “controlled” trickle charge.
That Optima 6v battery is at least 15 years old.
There were never any problems after hibernation. All I had to do was:
- prime the carburetor with a little gas (with choke open)
- pump the gas pedal a few times
- pull the choke closed
- crank the engine
- and, finally, on the first indication of firing, I released the choke a little
