Hi Garry, glad to help.
I agree with Jezzer B in that anyone who has a problem will normally get help even, when as once in our case it was just a corkscrew. More serious last year we had an awkward pitch and I was using the motor mover to get it on, when the thing stopped working. The man in the caravan opposite was only too pleased to help push it into place. That one was my fault as the batteries had expired, but it did not show until we were half on the pitch.
We have pushed other peoples caravan for them, lent the tin opener and the Calor Gas spanner as a matter of course. Not sure when we will get away to see this again though.
