Thinking of a new truck..

[Rtsbasic]

For sure the drivetrain will get spiced up a bit..would prob go for 2x 18 then..if budget allows 2x 24 and make an 12 cell pack up for another car. Does it really need the torque of an XL can? I've heard S cans work if you gear accordingly, so it'd move well on a L can? Just concerned an XL can eats more amps to get the extra torque, so shorter battery life? Would a 7XL have more or less battery life than a 11L under the same conditions with 18 cells?
