I understand it's a really simple job - that's why I always let the caravan service department do it. I don't/can't do anything that requires crawling on the floor these days, and try to avoid bending at the waist too!!
As for Basilbrush - careful with the sherry: 'You sohuld be albe'.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
