Looks like the Bates set-up from the U.S.? Bit out of my price range at mo` but does look well made. (As much as you can tell from piccies!).
Don`t know about carrying spare can of LPG tho!
I keep toying with idea of ski bolted to chassis under engine bay to extend just beyond original bumper. Would decrease approach angle a little, but if demountable, could be removed for on road use. Fixed steel bumpers would defeat use of crash cans wouldn`t they, and SRS would be less effective, I think. Any comments?
