I'm toying with the idea of getting a trailer like oxendon or tst for all my kit but i've got a few questions and would be grateful for some feedback. How many boards can i fit into the large enclosed trailer? How do i stop small bits getting lost at the inaccessible front end? How fast do they go on the motorway? Should i consider a braked model? Has anyone got experience with the mersea gemini? Anything else on the market that's worth considering?
