About
A White Mountains shop, and the owner answers for it
Wagner Motors is on White Mountain Road in Show Low, Arizona. Scott runs it. You may know us as Power House Diesel, which is the name on most of our reviews. Same building, same crew, same phone number.

What we work on
Diesel is what the shop is built around: Powerstroke, Cummins and Duramax, plus Allison transmissions and the heavier diesel platforms. Motor coaches and diesel pushers come through here, so do work trucks, fleet vehicles and fire apparatus, and so does the everyday general and gas work.
A diesel repair is a big bill and almost nobody can check the work themselves. All a shop can honestly offer is to explain what it is doing, put the number in front of you before it starts, and stand behind the result. That is what the four commitments below are.

The name
Most of our sixty five Google reviews were left under Power House Diesel. Nothing moved and nothing changed hands as far as the work is concerned: same building on White Mountain Road, same crew, same number. Every review on the listing has a reply underneath it, the good ones and the hard ones both.
“Scott took my diesel pusher motorhome in for a last minute repair, to change the oil cooler. Scott was super helpful and great customer service. The team working on the coach was super nice and did a great job. Thanks for fitting me in on short notice, allowing me to keep my travel plans.”
Before you hand over the keys
Four things we commit to in writing
You get the number before anything is ordered or started. If we open it up and find more, you hear about it before we touch it.
We find the actual fault before anyone talks about parts. Replacing parts until it stops is how a bill triples.
A real answer, not an optimistic one. If parts or the job move the date, you hear it from us, not at pickup.
If a repair is not worth what the vehicle is worth, we will tell you that instead of taking the money.
In their own words
What customers said afterwards
“Amazing shop! They are fast! Took my truck in both times had it back within the next day! Very honest and respectful! I would 100% recommend!”
“My truck kept throwing a generic MAF code. They went way above and beyond to diagnose and fix the issue when no one else could. Fair price. Very friendly. Highly recommend.”
