Wonderful people to work with. I have had both a Tono cover and mudflaps installed. They even helped finish up a taillight installation that I almost completed. These are the best people that I know to go get anything for your truck. I would recommend them highly!
Called the night before for a repair on the trailer. They were there at the exact time they said they would be and was very quick with the service. The technicians were very kind and polite, they even explained some parts and how they worked. Will definitely be back if i have any issues in the future when in the area.
Good job done. Friendly and fast. What else could I ask for.
I recommend for anyone needing upgrades to their vehicle. I was in and out in an hour for my lightning installation. I'll be back.

I purchased a roll up cover that came damaged from the factory. Jim was able to kindly replace my broken part with another one. Exceptional customer service.
Ordered a half cover for the bed of my F-250. The cover arrived the next morning. Appointment to install so I could watch it being completed, so I can remove later. The young man that sold me the cover as well as installed the cover was absolutely great. He explained everything patiently with excellent communication skills and instruction. This was a very pleasant experience THANKS!
Great work!!
Fast! My order was ready, and installed in less than 24hrs! (Would have been sooner but I had to wait till next day) Staff was very friendly, will definitely be back!
Luke went out his way to make sure we had enough space for the delivery for our new shed!! Thanks Luke! You're awesome!!!!!!!

Guys did an awesome job get'n my A.R.E. cap connected to my 2026 Chevy that I removed from my 2021 Chevy. Super nice guys in the shop as well!! Looking forward to doing more business with these gentlemen!
I had been saving money to have my control arms and ball joints changed as per tuffy auto. Their suggestion was questionable so I went to H&H where I was given an honest answer. They said that my truck was fine and didnt need any repairs. I cant thank them enough for their honesty being I live on a budget.
