No joke, the absolute best if you have a modified off-road truck.
I have a mildly modified Toyota Tacoma and they have been my go-to shop since day one.
I've had some repair work done at the dealership since I'm still under warranty, but even then I've had to bring it to Desert Rat to really get things sorted out. The level of expertise and attention to detail surpasses any other shop that I've been to in the Valley.
Most of the guys have owned and still own Toyotas so you know they are experts in that category.
Most recent experience involved a knocking noise that couldn't be resolved. I've been running around the Valley having the truck looked at by several shops to no avail. Desert Rat figured out the problem within 10 minutes and fixed it in 5. It was so simple they didn't even charge me. THAT is beyond good customer service.
I cannot recommend them highly enough. Ask for Chris or Brett.
