Aha! There's the rub - even a plug is actually two pieces, because what mates it to the pan? The threads! That's my concern when it comes to these - I agree the sheltered location of the plug on the PP is preferable too, and on motorcycles they're generally above where frames or pipes would hit for the very real concerns you bring up, yourself doing a lot of off roading! No offense taken at the choice not to rock one at all - every relationship looks different between people, so does every relationship with our PPs - as naughty as that sounds 🤣My main concern is replacing a one piece, fail proof plug, with a valve constructed of several pieces.
Some skid plates would have to be modified.
It makes more sense to install it on a drain hole that is on the side of the pan, like the PP
