My ARE truck bed cover was off line & not closing properly. The repair was not an easy fix but they took their time & made sure the bed cover closed perfectly & I can now lock my bed securely again with my key fob! The price I was charged was very fair even though the job was time consuming! I am a fan & will definitely be back! Excellent customer service. & very friendly!

I’ve bought 3 camper shells, 3 lift kits, a aftermarket bumper install, and a leveling kit from H&H. They’re a little pricier, but they do good work. No issues with any of the trucks I’ve sent to them.w

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.
