If the caravan has an Alko chassis I expect a mover will fit without any problem. I have fitted a mover to a Knott chassis and I had to make up some spacers, cost me 80p from memory. I think a B&B chassis might be more of a problem but I'm sure it would be possible with a bit of ingenuity.
The chassis of my Lunar Clubman is a TW Chassis LTD number 0096 7 84,and it appears that the position upon which it was mounted upon the late Metiorite does not extend far enough upon the Clubman.
------------- If if it aren't totally broken its probably best left alone.
