I bought a kings and fitted it to our old 83 Jayco pop up, I wanted a 3 x 3m as the legs would be that bit longer, but could only get a 2.5 x 3m one, I did mount it on the van at around 5 to 7 degrees angle out at the top to help the pivot down, that did help, But I had to duck tape some 25mm x 25 x 1m tomato stakes to the legs to reach the ground, its good to put up for a quick stop but I would not put it up in lots of wind and leave it, Craig
