If you need the power, a quality Dewalt 1/2 in 20V battery powered will have way more power than a similar corded model.
Yes, a quality 20V will hold a charge for a long time, while just storing. It will give near max power, right up to the end, when it gives it up.
Many HD trucks have a lot of torque on the lug nuts. It should be stated in the owners manual, that the pitiful factory supplied lug wrench may not be sufficient. A breaker bar with HD socket and necessary cheater will work for the amount of times that most of us have a flat on our TVs.
