Ah, I see. It's the depth of the tray that won't let you put it in...
Just out of interest, Lawrence, why not modify the tray/mounting? Surely it will cost you less than £350 and you then have common winches front and rear so if one breaks...
Otherwise, the TDS - I bought one of the early 9.5s. Just keeps pulling and pulling. Bought it cos the 12 wasn't available when I was in the market. Someone will correct me, I'm sure, but I think the difference between the 9.5 and 12 is the gearing, so the 12 will be slower.
