Brian was so very professional and knowledgeable of the job he performed!!!
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.
Great service as always. Needed something quickly, the store had it in stock and was able to pickup within minutes. Justin was helpful and very accommodating. Highly recommend!
Just had Arcane Warrior roof rack installed. Unbelievably quick and convenient service. Blake and Garrett were readily available and exceptionally personable. Highly recommend them for any and all truck accessory recommendations, provisions and installations!
Good pricing, fast service. Quality products.
Good experience. If you need truck accessories, these are the guys.
⭐️⭐️⭐️⭐️⭐️ 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. 💪
Very knowledgeable, great selection and fast install .
Fast service, friendly people and a great price!!!

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.
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!!!!!!!
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.
Had the pool parts we needed and a lot of other things!
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!
