Thanks everyone!
I do appologise as I have not logged on for a little while. We bought ourselves a second hand Seca 580. For the time being it will be our "holiday" home on our block down south and hopefully in a few months time when the house is on, it will be behind the car off on our first adventure! I have to sort out a couple of bugs in the electrical first so if any one here is clued up on this side of things, please look for my post.
