It's going to depend on the driver. Does it have a-trac? How much experience to do have wheeling the conditions you are referring to ? Lockers are really a game changer, on how you attack any obstacle, or adverse condition. You are allowed to use a little more finesse , instead of gas peddle. If you are experienced in using your brakes/e-brakes, while trying to climb, that helps. Lockers and a-trac, are a big plus, If you are questioning this and plan on wheeling a lot, may be you should let that cruiser go and try to find another one, with the right equipment from the start.
