Fast, friendly service! Eric was a pleasure to work with in taking care of an insurance claim for my damaged truck bed topper for my 2007 Ford F150. The new topper was delivered and installed the very next day! It looks great...a lot better than the one I had on there!!! I highly recommend Leer Truck Accessories of Conyers for all your truck accessory needs!

I understand now why LEER has such high reviews. Blake and Justin create an environment that is completely stress free. Their knowledge and communication skills are top notch. My trailer hitch install was complete in less than an hour. Make the call, you won't be disappointed!!

Wonderful people to work with. I have had both a Tono cover and mudflaps installed. They even helped finish up a taillight installation that I almost completed. These are the best people that I know to go get anything for your truck. I would recommend them highly!

Called the night before for a repair on the trailer. They were there at the exact time they said they would be and was very quick with the service. The technicians were very kind and polite, they even explained some parts and how they worked. Will definitely be back if i have any issues in the future when in the area.

I recommend for anyone needing upgrades to their vehicle. I was in and out in an hour for my lightning installation. I'll be back.
