Allen Mobile Diesel Truck • Trailer • Fleet Services

While doing a check on my son's Peterbilt, he found a large crack on the chamber that activates the right rear trailer brake. When NO other business would pick up the phone, Allen did. He came out, welded the crack, and was super fair on his pricing. Nice guy! This could have been an out of service violation as well as a dangerous situation if it wasn't fixed. Thank you so much, Allen Mobile Diesel Repair for your quick response and helping out a trucker that really needed you. A+++++ We HIGHLY recommend!

After not getting answers or call backs from several other mechanics, Allen Mobile Diesel called me back within a few minutes. I had a no start issue on my old John Deere tractor and they came right out and had me fixed up within a few hours. Very friendly people and I definiteley recommend them. I will be using them in the future.

The service and professionalism provided by Shea at Allen Mobile Diesel Repair was impressive.

After a speedy parts run, he was able to get my truck up and running again. The prices were honest and the customer care was exceptional. Allen Mobile Diesel Repair saved me a lot of time and hassle. If you find yourself needing roadside assistance in Northern Colorado, give Shea a call.
