Two friends of mine that I havehunted with almost every weekend for the past 10 or so years each purchased a fine looked, decked out "Bad Boy", dual motor "4 wheel drive" UTV in early 2007. I have no clue what they paid for these but I am guessing a bunch. Neither of them has their unit. I can attest to first hand is that they do pull out of the muck pretty easily.Seriously, from what I saw with these two units, these are great for good roads, even steep grades. But are useless under long duration, heavy strains ... and have difficulty managing deep muck that my Polaris Ranger literally walks through. Just seem to not have enough power to the wheels and work like that really sucks down the battery life.
