Hi, I am trying to buy a trailer online to fit a 2009 21ec. If any owners know the height from the top of the rear crossmember to the top of the rear bunks, much appreciated, it will give me a guide line so I can buy a trailer that I can raise enough to clear keel and get her out here,then I can properly adjust for permanent fit. If possible the same measurement on the forward end of the main bunk, I am not worried about the centering bunks. 8-10 weeks to build a new one so hoping to retrofit a used tandem axle trailer.Thanks text/call 250-812-1275
