Jim,
Re " If the area gets below 0 F. remove the batteries and store them in warm
areas" - the typical practice in southcentral Alaska is to charge the
batteries to 100% and disconnect either terminal (but negative preferred) at
the storage site in September and leave the batteries in the vehicle. Do not
disturb the vehicle until usually the Memorial Day weekend ( or, in my case,
late June as I have been a summer air commuter since retirement). At 100%
charge , the electrolyte freeze point is minus 76F. For a 40% charge, the
freeze point is minus 16F. I rarely see more than 1/4 volt loss over the
storage period for a quality, fully charged battery at storage. The record
low temp where I store my summer stuff is minus 38F.

I have very extensive experience doing winter storage procedures on both 2
cycle outboard motors, (big ones used on trawl net skiffs in salt water in
Alaska) as well as gasoline and marine diesel engines in boats used both
on fresh water and salt water. Procedures are similar. On outboards, turn
off the fuel supply after thoroughly warming up the engine, then run the
engine until just before it sputters, then spray quicksilver fogging oil
into the air intake without filters present until the engine runs out of
fuel and quits. There are sometimes manifold plugs as well as lower unit
plugs that must be drained of water, or they will freeze and break the
castings. Cover the engines from the top, leaving the bottom loose enough
for air to circulate. Waxed canvas is far better than plastic tarps for
this purpose. On marine diesels, pull the injectors and spray fogging oil
into the cylinders, and remove intake and exhaust coolant drain plugs.
Motor homes kept in covered storage? Drive em in and turn off the
ignition. Remove the negative battery cables. If the area gets below 0? F.
remove the batteries and store them in warm areas. 3 months or less?
Temperate climate, walk away and leave them alone.
