I'm not sure if it has Allen bolts or Screw knobs from the pictures, and I do not recall from seeing it last weekend.  It Does collapse as shown in the pictures and I'm not sure if it is one bolt or 2 bolts on either side to put it down.  We deal with a lot of boat houses and usually find no issues to fit.  The first right of refusal refundable deposit would allow us the time to explore this further as well any other options that may come available through the winter.  What have you found through your research on this model and are there any other questions you have at this point?
