Well we finally got the ALKO ATC fitted to the caravan on Tuesday morning (very morning 8:00 am). It was expensive 600 quid, though that included fitting it on the driveway, instead of 400 quid but a drive down south. I please with the neat installation, and I think its a confidence builder having it installed. It a cool technology solution, detecting sideways and pitching movements that are increasing, and then automatically applying the brake via a solinoid (actually it may be motor driven), this bring the caravan back in line. The only interaction with the system is a little multicolor LED on the towbar, its changed colo during a self test when connecting up. When it turns green, all is well. So for the last few days the caravan has been down outside our house, getting a little more attention that normal, a little heating, and refilling the drying crystals. I also needs a decent wash, but I think that will have to wait till after Christmas when I've got a bit more time.
