There is nothing like the luxury and power that go along with heavy-duty towing. 5th wheel RVs offer a deluxe, home-away-from-home experience unlike any other, while gooseneck trailers possess a strength that far surpasses most other trailer options. As with any trailer, however, 5th wheels and goosenecks must be equipped with the proper lighting and electrical systems, and tend to require even more complex connectors than a standard receiver-type trailer setup. Make things simple with a CURT 5th wheel / gooseneck extension harness. These wiring harnesses are designed to put an extra connector socket in the bed of your pickup truck while still retaining power to the rear connector socket mounted on your bumper. This is done by plugging into the back of the existing original equipment (OEM) harness and routing through the body of the truck to a hole in the truck bed, providing a connector that is ready to accommodate your 5th wheel or gooseneck trailer. This CURT extension harness is designed to work with 7-way RV blade connectors and comes in a length of 7'. It is compatible with a certain models of Chevrolet, Dodge, Ford, GMC, Nissan, Ram and Toyota (see application to verify fitment). When you need a towing electrical solution that allows you to switch back and forth between your receiver hitch and specialized trailer hitch, CURT gets you plugged in.

The guys at H&H went the extra mile for me, and I greatly appreciate it. Due to transmission problems in my son’s van, we needed a trailer hitch put on as soon as possible on my van so that we could go on our plans Vacation. H&H made it happen in less than 24 hours Ordering in and installing the required trailer hitch and electrical adapters. The installation was flawless, and the parts worked perfectly. Great job all the way around! I am very pleased!
Every review below is a verified Google review of an H&H store — written by real customers about the people who sold, fitted and stood behind their gear.
I recently had a tonneau cover installed on my truck and was very pleased with the customer service that I received. The associates were very helpful, were great to work with and did an exceptionally well job with the installation. I highly recommend H & H to anyone who is considering doing any truck upgrades. Also, an extra thanks to Cary for all the assistance he provided.
I ordered retractable running boards for my Bronco, then called H&H to install. Tyler got me in the very next day. They did a great job on the install and walked me through the details when I picked the vehicle up. They are my provider of choice for any future upgrades.
The showroom was very clean and the shop area was for employees only but the only thing that was concerned about was the price of the parts and labor but the in and out time was not bad
If you want amazing customer service definitely go here! They were extremely helpful! Thank you!!!!
Very friendly service very helpful
Very helpful and super friendly!!
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!!!!!
I was desperate, I couldn’t open my truck topper door. I stopped there to see if they could help. WOW did they ever! Very great service, friendly & mechanically qualified to help. 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
Great communication and customer service!
Bedliner installed, in and out less than 20 minutes
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.
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 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. 💪
Loved the bed cover they installed, will go back for extra grill lights
Great service , and follow Up. I will be back
I had a rear truck cover issue that had been recurring due to my daughter, slamming the top and it kept coming apart. I took it over there and Kory took care of everything for me as quickly and as efficient as I’ve ever seen anybody, do it highly recommend H&H covers they do really good work in Kory is one of the best Tech. I’ve worked with in a while.. Thanksguys.
They was courteous and professional.They help me and I appreciate it
Great service
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!!!!!!!
Had the pool parts we needed and a lot of other things!
Very knowledgeable, great selection and fast install .
