Sportsmobile / Field Van use rubber bung nuts that expand against the 1/16th" thick sheet metal. They fail over time and vibration since the sheet metal cuts into the rubber.
The issue with our pop tops and the legless or cantilevered awnings is the leverage of the of the arms when extended. An awning less than 6 ft projection is pretty much useless. A 6ft lever unsupported arm will stress the gutter and your mount a lot.
