Hear From Our Clients

Traveling in our motorhome and broke down in central Colorado. Called Miller's Repair on a Sunday morning. They called back and sent Travis to us, 1.5 hours away. Travis got us into our RV site and had to order a part from Ford, broken shift cable, could not put RV in gear without going under the RV and doing it manually. On Monday his partner Ashton was able to secure the part and have it shipped in. Wednesday afternoon Travis was back and installed the shift cable and we were able to do continue out trip Thursday morning. Both Ashton and Travis were professional and nice. They were the only company who responded on a Sunday morning. Call them if you need service, they are the best.

We had a motorcoach that had a DPF issue and had to shut down 35 miles south of Colorado City. We had a previous experience with Ashton and knew we wanted him to help us out. He worked many hours to get our problems fixed.

I was broke down on I-70 near Limon Colorado,I called this company, Mechanic showed up, in 1 hour, and I was impressed to say the least. The mechanic was a great guy, and very professional. he diagnosed my problem. Which was my alternator locked up and wasted my belts. Luckily he had the parts on his service truck. He replaced everything and had me up and running in know time.I highly recommend this company. Promptness, affordable, and reliable. Thank you Ashton for a great job. Thanks to you I was able to make my Amazon appointment on time. Merry Christmas to you.
