From page 40 of the owners manual…
“ Excessive snow loads can damage the roof of your TrailManor. If you suspect snow is coming, you should place the trailer under shelter or close the unit down to allow access to the roof for snow clearing. One foot of snow (or one inch of ice) should be ok. If the snow accumulation approaches two feet, or if the snow is excessively wet and heavy at one foot, you should remove the snow from the roof.
CAUTION: Do not attempt to close the trailer with snow accumulation on the roof. One inch of dry snow adds 40-60 pounds to the weight of the top. The added weight could cause the top to fall suddenly while being closed, causing personal injury or
trailer damage.”
But that doesn’t say whether that’s open or closed. That’s a lot of weight on the lift arms and the roof.
