I got mine and put the SERK in it for a week. First off, the SERK barely fits in the touring bubble. Based upon the pictures from the MoCo site, I have no idea how the hell they got an UC in there!
Also, you will need about three people to pull it over the top to keep from dragging the plastic (which sticks to chrome/paint/mirrors, etc...) over the bike and to zip it up.
BTW: The little foam "hat" filter sucks! My bike was filthy after a week, definately put a better filter on it. I cut up a new furnace filter and in put it up against the fan, which seemed to help capture the dust better.
It really needs to be bigger than it is!!!
I also put in a box of silicia gel and a hygormeter so I could control the amount of moisture in the bubble keeping it around 50%.
