Ditto on the braking. I usually do 150m round trips and pulling was never an issue with our Explorer. I was burning through brake pads and rotors though and eventually killed it. No issues with a Sequoia.
i wouldn't worry about how steep the ramp was for power as much as grip. i’d want a good 4wd with good grippy tires.
why not another 4runner ?
can pull extra slow so water drains as she comes out keeping the load factor down. but your not gonna get anywhere if the tires are just spinning.
