Has anyone come up with a good way to insulate the LGM fresh water tank for winter camping?
I have seen a few options. One is an insulated wrap that will go around the water tank. Two is to wrap the openings under the camper in Styrofoam panel insulation (clunky). Third is a little more extravagant but a better engineered way and easy to store.
The underneath of the LGM is merely plywood, sealed but not insulated I believe. When camping in the snow and very cold with the wind blowing under you unit, it will get pretty cold under your unit. Air Skirts https://www.airskirts.com/ seems to be an excellent solution (maybe a little expensive, but it depends), to camping in your unit in winter. I haven't tried these but I have a friend that uses them along with a small electric heater under the unit to provide above freezing temperatures. This also solves the problem of a freezing grey and black water tank.......nasty!
Just a few recommendations. Let us know what you choose and how things work. We're always looking for new recommendations. Happy travels.
