Do you have access to a power outlet? I plan to build a setup with a 25 gallon water transport tank and a self priming electric pressure washer. I'll either strap the water tank to a furniture dolly or get a cart to transport the full water tank to the garage as it will weigh nearly 200lbs when full.
