When ours was just an empty shell, I definitely noticed the tendency to spin-out on gravel, or lock rear brakes going down a steep hill. Those have both disappeared now that its well loaded all the time. My only gripe now is its resistance to get moving from a standstill. Even on small grades, it can take a fair bit of gas-pedal to get it moving, and when it finally does, it leaps forward. Nothing extreme, but it does make it tough to make small adjustments in your position, like getting up on blocks, etc. At those times, I wish it was a diesel. When I take it in for recalls, I will ask if there are any transmission adjustments that would help.
