OK, getting some good input here. I know that I don't want a car--to me they are not comfortable, or practical. If I'm going to be driving a vehicle around, it is so nice to have my gear and saws and take care of stuff while I run estimates, as BS in MW said. I am 6' 4" and feel like I am wearing a car instead of driving it. I could buy a smaller truck, but then I can't use it like I use mine, and I would really only save a few mpg's on it. I have my Dodge chipped, and if I drive it nice, I can get 18 mpg in town, but I usually don't drive it nice.
I have always had motorcycles since I was 17 years old, sold my last one after my 2nd daughter was born to keep me out of trouble, but I do know how to ride and have spent countless hours on bikes. I have asked 4-5 customers since I posted this about what they would think, and it is about half and half. Two of them said that they could appreciate the effort to save fuel, but that if they were new customers, they wouldn't like to see their tree guy show up on a motorcycle--wrong image. I hate to admit it, but I think they might be right.
