Wages for driving jobs vary greatly depending on many variables. Local route drivers are pretty much at the mercy of the local economy and demand. Teamster gigs pay well no matter where ya are. How hard you work physically, is absolutely NOT a factor in how much you make.
I work for a locally owned building supply company (picture a small Home Depot). We have to be competitive with other suppliers in the region, and provide the same or better service. I've been doing this for the same outfit for over twenty years, and love the job. I've delivered over a thousand whole house builds, from the foundation to the roof.
I'm pretty proud of what I do, because I've seen a lot of guys do a bad job of it. The money I make is fair considering the area I live in, but it's nothing to brag about. I have to have a Federal Crane Certification to do part of the job, and would make twice the money in the public sector, union jobs, etc.. I give my employer a good deal, and they keep me pretty happy.
Here's my two main rigs, One is brand new, drives like a limo, and is excessively mine. I about to turn 65, and starting to work a little shorter hours, and easier jobs. I still find myself reluctant to retire. jd
