Expert work. Quick turn-around. Have always trusted H&H with all my different trucks and the add-ons I wanted.

Jason at the Pelham location was great. After installation of a bed cover was done, we noticed some parts were removed but not put back in place. He went out of his way to fix the issue. Also some end caps were cracked during the installation and he is getting replacement parts for me at no charge. Will definitely go back to them the next time I'm looking to add some updates to my truck.

Great experience! Got me in at my booked time. Said it would take an hour, they were done is 40 minutes. Friendly and even showed me photos of the install. Highly recommend for bike hitch install.

I have been a customer of H&H for years and have always been given the VIP treatment. Staff are friendly, helpful and professional. Quality products and quality service. Go see them today, you'll be better off.

I must say I hate having to deal with things to do with the truck, however the sweetest gentleman was very attentive and not only put on the hitch, but put on the lift and found a needed screw, as well as he took the time to show me all the necessary steps to be successful. Great service, nice people, check them out for sure.

The staff is friendly and helpful. They went out of their way to make sure I got a warranty part replaced. Their communication is professional and they completed the work in a timely manner and it looks wonderful! Thanks!
