Mark, I met with them at the Annapolis show and spoke with them once or twice when ordering and they were fine , helpful.  They now have sold several to Amel owners and know which one to sell you. It comes in a box and is easy to assemble / install , I think total time start to finish was maybe eight hours . Would have been a little less , but I chose to several inches off the tubes to lessen the height . I built my own solar frame and installed three panels , they are out of the way and are never in a shadow . I incorporated davits into my S.S. frame and it has been great to haul the dinghy for trips between the islands.
