I might add that if you get into the hobby and decide to go 'wheelin' with some of your friends, make very sure that they know the rig you're driving is 2WD.
One run, I assumed with a quick visual check that all the trucks with us were 4WD. I announced that this was a trail that would require 4WD, tire size, lockers, blah, blah. Then when it got more difficult, the 2WD needed "little tugs" or more attention and help than anyone else, in fact, no one needed help except the guy with the 2WD. He was an above average driver, but still... it was only 2WD and that made a problem for the other 9 trucks on the run. Not that we were upset, just that we couldn't cover the ground that we thought we could because the 2WD guy didn't inform me (or I didn't confirm it?). He just thought it would be OK.
I've heard people say "my 2WD drive will go where most 4WD's go". Well, in that case, the 4WD's were not anywhere near their own limit, and they were just being accommodating to the 2WD guy! Plain and simple, a 2WD is NOT nearly as capable as a 4WD.
If you do go prepared with a winch, traction boards, diff locker, etc. you will be more equipped, but as
@The other Sean said, you will likely be less stuck than a 4WD will be, but don't turn into a liability being the only 2WD in a group of 4WD without telling the leader.
