Update -
We didn't get that much interest in a tube winch bumper, so what I've decided to do is the plate winch bumper and a non-winch tube bumper. Having it not hold a winch will keep it light, tight and relatively inexpensive. I'm always willing to reconsider, but for now that's the plan.
The Rev 2 prototype of the plate winch bumper is going to be ready for a test fit today. We are very close to being done on it.
The frame mounting brackets for tube bumper are done. I'd say maybe a month on that one.
