Whilst trying to position my twin axle on a rather sloping and bumpy field the spare wheel on my 4 x 4 caught the front end corner of van and put a hole through the front. It is a Lunar Lexon 640. Any one have an idea whether this can be repaired or will the whole front panel need replacing. The crack / hole is about 5 inches long and is between the locker door and the sdie of the caravan. Where it bent in are several cracks the longest about 12 inches other wise no other damage.
