Hi, I thought I would throw in my two cents about winter storage. Here, we do not use the trailer in the winter, so it stays in storage from November till the snow goes in March/April. We keep it in our garage the rest of the year, when the van (TV) can be kept outside.
For the past two winters in northern Alberta, we have stored our
Boler in our back yard under a lightweight 10 by 10 foot square "screen house" that we bought for about 50 bucks at a discount house. It is a gazebo with screens on all four sides. My wife is not crazy about the look in the yard, but it saves us about $400 in storage charges over a winter. It has metal poles that support the roof at the sides and from eight edge locations joining at the centre. We get significant cold (-40 degrees) and some snow (a few feet). Last year I brushed the snow off the roof once, but otherwise not a problem. I found that the roof poles at the edges were within an inch of the edges of the trailer, although the centre was plenty high enough, so I raised the house up off the ground with small pieces of 4 by 4 wood and staked it down securely like a tent with no floor. We had some winter storms but the house did not blow away or become deformed, and worked perfectly at keeping the trailer dry and free from snow. Our location is fairly windy, which helped to keep the snow off the sloped roof. Air circulation was great, so I did not have to worry about condensation as I would with a tight fitting cover.
This particular house has two movable side panels that I put on the windy sides, and two zippered entrance doors, one of which obviously went near the trailer door. As a bonus, it allowed me a dry area beside the trailer for entry when the ground outside was covered with snow. Our yard is quite sunny, but the
tires were always in the shade because of the screens or panels, so UV was taken care of. Our hitch stuck out the front, and I covered it with a tarp. All in all, it worked out great, and I will get another one in a couple of years when this one gives up. We also use the screen house in the summer for its intended purpose at home, but not camping as it is too bulky to carry around.
