I've worked DOE, Commercial and now reside as a house tech and must say there's advantages to all. My family usually traveled with me so DOE in the latter years was the option, however I cut my RP teeth in commercial power in the early days (early 80s). As a contractor you always have options to utilize at anytime to fit your current situation. As a house tech, those options aren't always in your best interest but the bennies are a fine substitute for options.
