When we got our DISH TV satellite receiver last year I also purchased the free standing tripod so the receiver can be located away from the RV with a clear view of the southern sky. The challenge with this is when we are traveling and staying in rest stops and Walmarts I can not set up the receiver so we can watch TV. The Winegard Pathway X1 receiver has a roof top mounting kit available for $100.00. However it is designed to be a permanent installation. Here is what I came up with so I can mount the dish on the roof and remove it whenever I want. CLICK
I went up on the roof today to check the mount and everything is good. The only thing I added from the original design is after the two outside locking screws are tightened into place I add a wing nut and spider lock washer on the inside of the bracket or end of the bolt. I added this extra nut and washer to ensure road vibration did not allow the bolts to back out.
