It's not exactly air tight, but I do see some moisture build up inside these past days of 50 degrees plus, but that is something to consider. Have you put vents on one of these yet ? It does have space where the tarp hits the ground since it shrank a little over the years.
Plowing 3" of snow Thanksgiving day was great. It wasn't enough to justify taking off the BH and putting the huge snowblower on for a little snow, so I just curled the bucket up a little, put it in float position and drove up and down my driveway in high gear at prob. 6-8 mph. It was awesome ! Took me 1/2 hour to clean the driveway. /forums/images/graemlins/cool.gif
