We just bought our first RV (an R-Vision Stratus 291) and will be picking it up this week. Lots of questions of course, most of which we haven't thought of yet, but at present I'm looking at security. The Stratus has a Thatcham approved alarm/immobiliser fitted and I'm also investigating a neat low-cost tracker solution that I came across today, but what I'm interested to find out is where I can get those large post-code letters that stick on the roof. Several people have suggested that this is a good idea, but I don't have a clue about who supplies them. If anyone can point me in the right direction, I'd be grateful.
