WhoooHooo! That's the dilemma I face every now and again. Your "dukes" style doors would greatly inhibit my hops and barley intake which would in turn greatly reduce the joy of said adventure. I will figure something out that is safe yet functional, you can bet your best case of beer on that.
We just finished making a few aftermarket cages, bumpers and door bars for the prowler. Thanks to Glen our customer in Vegas for the vehicle loan for development. Thought I would share.
