Just reviving this thread to offer some info. I bought the Xbulls because I don’t generally find myself stuck enough to justify Maxtrax. I treat most of my recovery gear as an “in case”, since I often travel solo throughout Alaska and I try not to get too crazy. I’ve used my xbulls twice. The first time they performed as they should, although they lost some teeth in the process. The second time I found myself stuck in mud the consistency of axle grease in a rainstorm, with large rocks and and deep ruts . I used the xbulls throughout the recovery (which saved me from a long winch pull). Afterwards, both boards had large cracks running lengthwise, numerous teeth missing, a 1”x1” square missing from the middle of one of them, and a 4”x2” section missing from the end of the other.
I only have a Tacoma that isn’t loaded all that heavy. I travel solo and don’t try to thrash my equipment, and try to use finesse in technical terrain. The xbulls did their job, but they got trashed in the process. If you purchase these as an “in case”, they’re not bad. But if you plan on multiple recoveries I’d go with a more durable option. Hope this helps someone!
