Thanks to the people on here - our water is now running (turned out to be faulty pressure switch) and the lights are working (erm something to do with 12v and 24V working different lights and we'd switched on the wrong one) And our new metal trim (due to an unfortunate incident with the gate post) arrived today (thanks Michael!). Only thing was they'd only sell us 5 metres and we only needed 1 metre but as my friends at work said better keep spare incase it happens again - nice! We'll be all set for our second attempt at caravanning at the end of May. Lets see if we get it right this time.
Thanks again for all the advice folks!
(Probably need more after the end of May)
