Great job. My mechanic Mitch did an incredible job. Arrived exactly on time. Finished the repair in record time and the price was very reasonable. And all on a Sunday morning. Great job! Keep up the awesome service.

Thank you so much to Greg. We had an emergency after hours and he quickly got us and our horses back on the road. We are beyond grateful.
Tim Braun
They got me right in when I needed a repair during a trip. Fair pricing with quality work. Went there worried since on the road repairs can go so wrong but left very happy.

I can’t thank Greg and the entire team enough for the outstanding service they provided. If you’re looking for honest, reliable RV service and are anywhere near Janesville, I highly recommend Block Diesel. Their expertise and customer service are second to none.

One of my brake chambers broke as I was driving down Interstate 39 by Janesville. I called them after doing an online search. Josh came out in about an hour and replaced my brake chamber fast! Thank you Josh!
