I do low voltage installation and service. the most I carry around is my tools and a duffle bag if I am staying the night where I am going. Sometimes will carry a 6ft or 4ft ladder which fits in a car if the back seat lays down or just about any wagon.
I have 2 trucks right now and its killing me in gas. One is still under the knife for a winter project. and the 4x4 S10 is is about to break 100k miles in the next couple weeks. I trade/borrow my dads Kia Sportage at times which gets decent milage.
and i forgot about the element, I will check into those. I like honda I have owned 2 and they run forever. I had a civic and a CRV a few years ago.
