Testimonials

On 5/24/2026 Anthony K. had this to say:
Just left for a two month road trip and the turbo on our 2015 Ram Cummims decided to die. S and K went out of their way to get me the only turbo in Phoenix and install it the very same day. They stayed past closing for us just to get us back on the road to continue our trip. This was also a holiday weekend. It would have been easy for them to say no. The quality of their work was stellar. No issues pulling our fifth wheel the next day. I can't thank the guys there enough for going above and beyond. Highly recommend Chris and his crew. Six stars was earned! Anthony K. Very satisfied customer

On 4/28/2026 Larry T. had this to say:
2006 Tiffin Phaeton Allison MH300 wasn't shifting properly. Chris diagnosed the problem, and completed repairs at the proposed price. Along the way, Chris found the solution to an intermittent problem we have been having with our CAT C7 for two years (4 prior shops could not find). We would recommend Chris to anyone with a DP.

Absolutely love S&K. I have a motorhome that has dished me a lot of issues the past few months and the guys at the shop have taken very good care of me and done an exceptional job on the motorhome to keep it road worthy for my family. Special thanks to Dave!

On 11/28/2025 Cemal had this to say:
I stopped by on the way. I had an X15 engine that needed urgent repair, and it was done right away. It was done at a very reasonable price. David in the office is a very nice guy. May God bless people like him. Thank you. I definitely recommend you.
