I came a very long distance and worked with Shane over a three week period, and I must say from day one through the day I picked up my unit, the service was outstanding. Not only do they sell superior products, but the customer service is top-notch. Thank you, Brechbill Trailer Sales!

Purchased a new Eby dump trailer. Great experience during both a phone order/ purchase, and on my pick up / delivery day. No hidden fee’s or surprises. I would recommend them as everyone I encountered was very positive and helpful.

We brought our B wise dump trailer to Jud for things that needed fix and he did an awesome job. Also we had a local Chevy dealer install a brake controller on our 2023 Tahoe, after the 3rd controller, we had Jud look at it. Jud found that the Chevy dealership installed them wrong and it was burning the brake controller module up. Jud took the time to replace it and install a new one for us, he is very professional and explained everything to us. 10 out of 10, we will be back to Brechbill for anything trailer related. Jud definitely earned our trust..

We purchased an enclosed trailer in a matter of three hours. Two of those hours were the drive to the shop. We were approved in 5 mins with Ryan’s help and Steven was amazing with helping us hook up and explain everything in detail. Highly recommend. Friendly and knowledgeable staff with rapid results! You guys rock!!!
This product totally did the trick for my Ford SD replacement.
This set comes with an RV plug. But hey, if you want, you can change it out with that fancy new Ford multi-plug that fits both the RV and flat 4 plugs. And the best part? It comes with all the necessary relays. Can you believe it? The dealer wanted $180 just for the wiring harness. This is totally a steal!
Worked perfectly, no problems
Cool product. But it wasn’t wired correctly for my 03 F350. I ended up having to swap the wires around.
Worked like a dream with my 2001 F250. Just a heads up though, it doesn’t come with the extra wires for a four-pin connector. If that’s what you need, you might need to do a bit more searching.
