    On Behalf of Black Eagle I must state that this shop did an amazing job with our truck that was broken down. Steven was very helpful and couldn't be more happy.

    Best there is in the heavy truck and rv (chassis) repair business. I had an exhaust manifold leak on my Cummins ISM450 (Newmar mountain Aire Class A). I was so impressed with the skill level of Steve’s team that I stayed almost 2 weeks while they addressed a number of other maintenance issues. If you stop in, ask Steve’s brother Stan for a tour of his cargo trailer.

    We got stranded on spring break 9 hours from home and were told they were the best with in 100 miles. All I can say is that they are absolutely amazing. I feel like they went above and beyond to help us. They let us all hang out upstairs where the girls could play, watch TV, and color. They were able to get us back on the road the same day. When we heard our truck start up I had a world wind of emotions because I was so happy. I thanked everyone who was there the mechanics with oil on them and all with a huge hug. People like them are the ones who impact you the most and make you realize there is still good in the world. Thank you all so much for helping us we truly appreciate it from the bottom of our hearts.
