Here's what we 'plan' to do, at least this season.
We don't use the on board water system so winterizing that is a NON issue.
Our neighbours have opened the door(s) to his shop (in which they store their Trillium
and hot rod) for us to store our trailer in with theirs, but here's what I plan to do to ours.
Completely remove everything out of the cupboards that doesn't need to be there, and leave ALL inside cubby hole lids off and doors open. Seat cushions are removed as well as the bed (on rear dinette). Small propane
tanks at front of trailer will be removed (for safety sake of the neighbors trailer and hot-rod) but we WILL leave the battery
in its box on the tongue and it will have a battery
maintainer on it. The trailer will be leveled and slightly raised to ease the load on the axle
. I will place a piece of treated 2X12 wood under each tire so as to NOT absorb any moisture (from the concrete floor) into the tires
. The curtains will remain hung, parted slightly and all windows
left open a titch as will be the air vent.
This 'practice' is basically what I'd do if I were storing the trailer here at home outside but under a shelter, except I'd have a ceramic heater going and close the vent and only leave one window cracked. "Dri-Z-Air" is also known to be used in these parts too, BTW!!
