you can use the MoJack XT or MoJack Pro....NOT the MoJack EZ
I have the MoJack XT for my X-One, which weighs in at 1260 pounds or so......I called MoJack and asked the guy which one. And, after some figuring (approx. 30% of the weight is in the front) he said to buy the XT.
The thing works great, I highly recommend it!!!
