For just a few lights and such look at just getting a converter for the car or truck. Generators are great and all for large projects but you are looking at a ton of extra expense as well as noise. if you really want one and are cool with it check out the Honda Super Quiet Light Weight Inverter 1000W 120v Fuel Efficient Generator. This is the model we use for our small shoots and works great and quiet. Keep in mind if we have the option just use a converter in your car.
