Got back from camping at Pottsville and while cleaning the van, noticed one of the front clamps was out at the bottom. Tightened the screw and found that it was a bit loose. Checked the other screws and found only one was tight and the others were broken off so were only holding into the outside sheeting. The 3 screws that were broken only had about 6mm of thread on them. Have to check the others yet but thought I would let people know about it. I will have to shift the clamp as it is impossible to get the broken bit out.
