Al,
SO you think if I pick up a shadow bracket, I can make it work? Do you have a cheap source so if I can't make it work, I'm not out much?
Benny, I asked them(New Bonneville) about the Easy Brackets, they state that they work well on small to medium bags. Not to work with Large, let alone Jumbo. One of the issue is that there is no side support kepping the bags from going in and out. This would give a lot of stess to the mounting points. Fashioning a 'plate' to help support it sounds like a temporary solution and only adds weight. I'm not sure it is the best solution. I think having a few rigid mounting points is a better solution, especially on a long journey. I'd hate to be 1000 miles from nowhere(Dwight Y) and have the bags fall off.
