My name is Mark Lehrer - owner, driver, dispatcher, and accountant at Rock Beacon LLC. I have lived in Thief River Falls MN my entire life. After spending over 20 years in corporate accounting, I gave up the office life for a life on the road. I've been driving trucks since before I was old enough, working my way through high school, college and evenings and weekends over the years. After the office, I spent some time as a company driver, did some teaching at a community college, and did some consulting.
Then I went on my own.......

In the spring of 2020 I purchased this Volvo from my brother and signed on with Knife River Materials for the summer construction season of 2020 and have continued since.

I work with Hasbargen Logging in northern Minnesota hauling logs from the woods to the mills during the winter.

Between road construction and logging seasons, I haul various freight nationwide.

In 2023, the trusty Volvo's engine gave up. I decided to let it go and operate only the Peterbilt

I mostly haul asphalt in MN and ND during the summer construction season.

I feel fortunate to work with guys that have become good friends.

In 2025, I purchased my own trailer for winter log hauling. I enjoy being in the woods working with a fun crew. As a bonus I'm close to ice fishing on Lake of the Woods.

It is good to have a truck capable to haul some of the ice fishing equipment to the lake in the fall.

Between construction and logging seasons, I haul mostly stepdeck freight. My favorite route is to Alaska.
