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.

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.
H&H has now come to my family's rescue twice. Each time, due to unexpected circumstances, we needed a trailer hitch attached to our vehicle virtually immediately. Sean, the manager, went over and above to get the parts delivered overnight and get the hitch, including all wiring needed for the lights, installed the next morning after his first scheduled job. These are your guys if you need work done right and done quickly!!!
Excellent work,, outstanding staff, 5 STARS customer service ON ALL LEVELS!
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
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.

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!
Great sales and installation teams. Fast , efficient, and professional.
