5th Wheel rails installation I would not recommend. First off, I had to drive 26 miles each way to sign a waiver for them to cut 2 slits in the bottom of the truck bed, which it tells you to do. When I picked up my truck the 4X4 did not work. After hours of troubleshooting I found a blown fuse. After further inspection I found that they drilled into the wiring harness that caused the problem. No mention of any issues when I picked up the truck. The front outside brackets are clearly marked, passenger side and driver side. They were installed on the wrong side. Step 1 in the instructions that I provided says; On the inside of the left vehicle frame is a wiring harness that is held in place with plastic clips. This section of wiring harness must be moved aside by removing plastic clips from frame. This will allow the hitch parts to be positioned cor-rectly on frame. Update; Kyle, the store manager called me on Monday 9-15-2025. He said his technician did not drill into my wiring harness and wanted pictures. He also stated that if they had done that, they would have told him and me. Well , I sent him the pictures. Kyle said he had to send them to corporate, not sure why? The wiring was not damaged when I dropped the truck off. Now it is. Who is responsible?
