have done it quite a few times dirt, as long as you have the space, it is way easier, and saves time. I think I have at least a dozen or so installed this way in the last 5 years, and not one problem. been using s+s for the last five years, One thing i will say about the s+s, is if you get the smaller units that are for your specific horsepower etc, the lugs are quite small, and when you get to the job you will be fighting the wiring, so much easier to buy the biggest one for a couple hundred extra bucks, and save a headache. plus in my opinion it should last longer.
