I'm anxious to hear replies to this thread also. I don't know anything about ATV's/UTV's except that I don't like the prices. The Chuckwagon looks good and the price isn't horrible. Also, up until 2 weeks ago, I didn't know anything about golf cars either. The my neighbor gave me his. '88 EZGO in disrepair. Now I know enough about golf cars to be dangerous. A day of engine work (9hp 2 stroke), a used $30 top, 2 new tires, homemade flatbed, offroad lights, I've got a very capable little machine. VERY surprisingly, I have found it to do extremely well off road. I have rolling land with a cut bank in front of my house and a small dry creek. It pulls 1.5:1 slopes easily ... with a 15 gal spray rig in back.
The Chuckwagon seems to have all the hot golf car add-ons, lift kit, big tires, cargo bed, etc. But that diff lock is a huge plus!
Good luck with what ever you wind up with!
