NOTE: For questions regarding the trailer build and details, please post them in the thread and not as a PM, I receive quite a few questions on the build and would love to have this be the place of record. Thanks, Jeremy

#1 for the steel tube stock, I chose the outer DOM steel tube of 1.75" OD so I wouldn't have any binding on a welded seam. The inner tube, was trial and error till I found something that worked well. The center puck is made out of 3/16" thick steel, using a hole saw and drilling and tapping the holes to secure the gas struts to each other.
#2 I made the pucks at the top and bottom out of UHMW available at any plastics supply house, or I picked mine up at Rockler woodworking.

#3 The top I used is a recycled roll top, but due to the huge amount of space it takes up, I have just used the light weight aluminum as a deck. I don't open the top, everything is accessed from the rear door.
Coupling the two gas struts: if you aren't as conscientious about closed height then you can use a coupling nut, in that case make sure both your upper and lower gas struts are the same thread size and pitch, i.e. M8 or M6.
Thanks for your service across the pond.
