Started out with an axel I had laying around...turned into a 5x8 plywood deck with 10" side rails and a removable "rack system" up top to hold the yaks..it also doubles as a storage rack when off the trailer. I used all light weight material to keep the weight down as im usually towing with my 4 banger. The idea is to use the lower deck for all my gear, camping goodies and etc. I'll post more pics later.
