That thing is sweet. It make me want to go smash thru some small brush and sapplings. Awesome!They also have one for 80s style models, which would probably fit your 73-91 style Suburban better. And my '84.
For $1400, no drilling, no welding, sounds terrific, except for $1400 I could buy two more Suburbans like mine...but that's the style I'd be looking for...
