Thank you Zach, Thank you Dan, Thank you Jacob and thank you impersonator radio voice Tim for a great, quick, thorough service. I really appreciate it. I'm giving this company a 5 Star rating. They're reliable. They stay open late. They'll even offer you a ride to the hotel if you have to stay over a night while they do repairs. I really appreciate the hospitality. Thank you all!!!! From BGC Freight & Logistics.

I had a brake can go bad on my truck shortly after hours. I believe the mechanics name was Keith…can not remember for sure, anyhow, he showed up with the service truck, got my truck all back up to operable condition in a very short amount of time. The bill was exactly as we had talked about on the phone, no hidden fees or dumb stuff like some shops. I'd recommend them any day. The mechanic was great, very knowledgeable, very personable.

I contacted Block Diesel after discovering that I had a fuel leak in my class A RV as I was traveling through the area. They sent me out a mobile mechanic, Mitch, who was extremely professional. After examining my problem it was decided that I would be better served in the shop. He called back to his boss, Zach, who said they would fit me in if I could arrive early the next morning. I arrived early, as requested, and was met by Zach, who assured me that Mitch would be with me as soon as he wrapped up a task ahead of me. He assured me they would have me done by noon. Mitch finished up and gave me

These guys are awesome. I was forced to call TA first. Blew airline underneath my trailer around 4am from road debris. Got a song and dance and said no one was available to help me til after 8am, even tho website said they were 24hour repair. So called Block, and they were there within the hour and had me on my way within minutes. Super nice guy. Very next day, I blew a brand new tire on same trailer, lots of damage. Forced to call dispatch again, cuz I guess Michellin has some new roadside assistance program now that farms out the work- its a joke. Both TA and Loves said it was gonna be over a

Don't take your truck there they will give you an estimate and when you pick it up it'll be thousands over the estimate because they change parts that don't need replaced or even tell you until your there to pay the bill and the prices are bs you can get parts cheaper from a dealership. $6000 and couldn't even hook the batteries up correctly and week later I'm having issues with crap they took apart and apparently couldn't put it back together right. They will never touch my truck again.

After reading the reviews, it doesn't surprise me as to the mentality of some drivers. It's hard enough to find a good shop on the road, let alone find one that will work for nothing as some of the reviews I read would have wanted. I have used these guys a couple of times, once over Christmas when I was frozen up. Tech came to my truck and got me going in a reasonable time. Costs was competitive and service was very good. The last time was an anti freeze leak and a power steering problem. Yes I sat for a couple of days but only due to having to wait for pump to be overnighter. Work was done right

DO NOT USE THIS COMPANY...... My driver had a leaking water pump. Quoted me a price of around $400 and we agreed. Their mechanic took twice as long as they stated so therefore they charged me double what was agreed on. My truck made it less than 3 miles down the road when my belt tensioner gave out. (They said it went out due to normal wear and tear) There was nothing wrong with it before they worked on my truck. They sent a service truck out and charged me another $600 to fix what they broke. COMPLETE CROOKS........This is the type of company that gives mechanics bad names. Took advantage
