I need to change the leisure battery on my van, it is located under the drivers seat. I have looked at how to get it out and wonder if anyone here knows how to remove the seat to allow access. The seat appears to bolted to the frame using 4 alan type bolts though the swivel. However the nuts are hidden behind carpet covered ply wood panels that are themselves trapped behind 2 lugs and seem to be put in when the seat frame is installed, and I cannot get a spanner on them. The seat frame appears to be held to the floor by 2 large nuts which are easily accessible but I cannot see what secures the rear. So I do not know whether undoing them will enable removal of the seat and frame complete. Is there any easy way of removing the battery?
