You can’t tow a M3W on an A frame, in fact you’re not supposed to tow it at all although it may be possible if the back wheel was in the A Frame? I don’t know of anyone who has tried.
I was after a trailer for months and the one I found most suitable was by Lider, a French company with lots of agents in the U.K.. They appeared to have the only one that had a 6ft wide tilt bed without having to go to 16ft.+ length. reasonable price too as trailers go.
I eventually purchased an old Dastle Racebox off fleabay, only 6’6’’ high so it fits in the garage. PRG trailers will make you a lowline covered trailer bespoke for the M3W. Gajet here on TM has the ex MMC one, perhaps he’ll post some pics?
