[A1 Dirt]

The answer is No.

The info with the kit says it is dual voltage - 7.2v or 12v. This is only true with an empty truck. Even then, 11.1v will raise the bed in 30 seconds, while 7.4v takes 60 seconds.

With a full load of dirt and rock, with full meaning nothing higher than the sides, 11.1v will raise the bed in 50 seconds. 7.4v will only raise the bed half way and takes 90 seconds to do that.
