No, but I googled it and it looks like an essential tool for a come-a-long. Is it new, as in the last decade or so? I knew a guy in the '90s who HEAVILY modified his jeep (see below) and he didn't have one of these.
Just the modifications I remember: dual battery system, compressor, granny gear, scuba tank (compressed air when he had to work on the engine), the gear box from a dodge truck, custom-made gears for said gear box, a fuel injector to replace the carburator (this was an Wrangler YJ). The come-a-long, tow hooks, lift kit, exhaust, etc. seemed downright pedestrian by comparison.
