more than 2 years later, you've likely got it figured...
how about pieces of aluminum, pop riveted on to the outer latch, sloping in to very close to the side of the camper ?
then you can really get into plowing Alders
Still a problem. I've had to remove branches and bend the center tab back a few times. If I were handy at fabricating parts then I could come up with a better latch design. I'd probably use a strap attached to the top that connects to a latch below. That would get rid of the tab and lower the reach height which is too high.
