As soon as I hit the road I knew I found my niche. It did take some getting use to not having the luxury of a shop and all it's equipment. But you learn to adapt very quickly. I did have some older road techs that helped me along the way. We do the same in our company. Our communication is pretty high tech, so a tech is only a cell call away. We have camera phones so if your stuck and have never seen this " thing", take a picture and send it to any techs email address. We have tablet PC's and color printers in every van with cell cards so we're always live. Thats a far cry from the old Motorola 2 way radios we used in the late 70's.
And as far as ever thinking about going back into the shop - never.
