I did a run in the gravel at Raptor Assault in 4a / Sport and it worked pretty well, but for my money - Mud/Sand. 4a is not a subaru like all time system, it’s on demand and if you overdo it the truck will get mad at you and put you in 4h. The difference between sport and M+S is that sport is a road oriented mode, M+S is an off road oriented setting.
