Go to LEER Truck Accessories by H&H for your truck needs. Luis and Justin were perfect, I purchased my own running boards to get installed on my truck. Let’s just say the prices were VERY REASONABLE!!!!!!!!! My appointment was at 2:00pm and out with my truck at 2:45pm. Job well done guys. We just moved to the area and I was looking for a truck accessories company. You cannot go wrong with LEER Truck Accessories by H&H. So if you are in the area of Marietta off of Cobb Parkway stop by and check those guys out. I will definitely be back for more upgrades for sure. Thanks you have a customer for life!!!!!

Had the door open & repaired in less than 15 minutes. I tried to pay & they said; “no charge”. I’m definitely going back there! Mike H

⭐️⭐️⭐️⭐️⭐️ WOW – That’s How You Stand Behind Your Work H&H installed my airbags last year, and recently I ran into an issue where they stopped working. From the very first call, they were incredibly helpful and patient, walking me through troubleshooting over the phone trying to save me a trip. When we couldn’t get it resolved, I called first thing Monday morning and they had me scheduled right away. They got the truck in, diagnosed the issue, and replaced the parts — completely under warranty — no hassle, no excuses. A couple hours later I was back on the road. That’s rare service these days. Professional. Honest. Stand-up guys who truly stand behind their work. H&H is hands down the place to go for all your truck needs. 💪

Lucas the sales guy did a nice job walking me and my wife thru the process he kept his word by keeping us up to date on the building process….Justin and the crew did a great job installing our building on 9-17-2026 building looks even better then in the 3d image website they where professional and respectful the only thing I hated for them was they played music while they were assembling my garage and my neighbors called corporate on them and corporate instructed them to turn it down we how ever didn’t mind the music at all so if your reading this Justin we appreciate your help we love the garage thanks -the McIntyres

Trevor and his team did an outstanding job delivering my new 10' by 16' aluminum shed to a very tight delivery location. The shed is outstanding and I was glad I went with Thrifty Portable Building. I highly recommend them if you are looking for a portable building.

I had a problem with a tonneau cover almost blowing off. I patched it as best I could and visited H & H in Muscle Shoals to see if they could fix it even though it had been installed at a different H & H store. Rusty was kind enough to fix it easily. Highly recommend this individual.

Stopped in to inquire about a new truck bed cover for my husband’s brand new 2500. Staff was very helpful and gave us options of what he was looking for. Surprisingly the cover my husband wanted was in stock. We were in and out in 30 mins with a new installed truck bed cover. Amazing service.
