Unless you are one of the lucky folks who can by a new rig and a new mess of payments every few years, you have probably realized rigs generally last longer than trucks they're mounted on. At some point it dawns on you that ol' truck just isn't going to make it to the next job. The rig is fine, you've done your maintenance, and probably upgraded it just the way you want it, but the truck is DOA. Time to re-mount the rig and get another life out of it. Before you grab your cutting torch and start whacking away, there are a few questions you should ask yourself.
First, should I go with a new truck, or a good used truck? If you work several states, and run a lot of miles between jobs, a new truck might be justified. But, if you mostly work within 50 or so miles, a good used truck might be a better investment. How many miles per year do you drive? Since most of us are probably going to end up re-mounting on a used truck, I'll limit this discussion to them.
