Leer HF650M Hard Folding Tonneau Cover

Let me start off by saying this is not my first folding cover that I’ve purchased and installed. It is the first Leer product I’ve ever purchased. My criteria for a cover required it to be strong enough to keep the Maine snow out of the bed and allow full access to my 5th wheel hitch in my 2024 GMC 3500 crew cab SLT with a standard bed. I’d say Leer engineering needs a few lessons in the basic engineering principles of form, fit and function! This cover requires significant design improvements to be considered a quality hard folding cover. According to the Leer website the HF650M should fit this truck, but nothing could be further from the truth. It is approximately 1 inch short. I’ll give kudos to the Leer packaging engineer for designing a sturdy and robust package. However, don’t expect much in the way of installation instructions. The directions and on-line installation video are pathetic. They are incomplete and don’t cover all the components included in the box. The provided rails have a nice rubber seal that makes contact with the bed rail, but as the picture shows, barely sits on the bed rail. There should be at least ½” to ¾” sitting on top of the bed rail for strength and adequate width of rubber to properly shed water. The rails come in 2 pieces rather than a single extrusion. This is a design failure simply done for the convenience of a single shipping box. The rail clamps are fine until you get to the clamp on the rear left side intended to be installed through the stake hole. It is impossible to install the rail clamp provided due to the standard factory installed grab handle (see picture). This leaves several feet of the rail on that side with limited support since an additional/alternate clamp is not provided. The inner and outer seal at the cab end do not prevent water from entering the bed because the inner seal does not contact the bed (see picture). If the cover was just one inch longer this issue would be resolved. The outer seal is not wide enough either to make full contact with the rear side of the bed. This leaves a significant gap for water to enter (see picture). The seal at the tailgate is acceptable. The panels themselves are simply too thin in my opinion allowing them to sag into the truck bed. The picture showing the puddle of water is evidence enough. I have no confidence the panels won’t cave in when the first snowfall in Maine arrives. When the cover is propped up against the rear window the brake light remains visible. However, it should be noted that the rear bed camera is blocked. If I hadn’t destroyed the box while opening, I’d would have returned this cover.

This Leer Tonneau cover is extremely nice and fits exactly into my 2023 F150 truck bed. I like the way to folds and locks and it has a very sleek look. Auto Accessories Garage shipped it out very quickly and I am extremely satisfied with my purchase.
