Cap is flimsy and cannot carry any load. Why do they offer a Thule rack for the top if it can't carry much weight--useless for most purposes. Leer rep told me the core material of the cap is cardboard. Based on how flimsy it is, it must be so. Tailgate will not stay closed. Electric lock failed. Ram was secured with one screw that loosen every time it is used. Poorly desiged mechanism. Product came with defective window screen. Took me 2.5 years to get my replacement. They shipped it after 1.5 years, but nobody notified me it came in. Sat for over a year. Even with new screen the screen is not held in place at enough points to keep out insects. Large gaps between screen and window. This window is nearly 7 feet long and there are only four brackets to hold it tight? Come on! what were you thinking? I asked for more brackets and these were never provided. Nut securing frame was striped and unsightly. This was the worst choice I could make for a truck cap. My old one that cost me $50, was stronger, had screens that work, although not as good looking it was not bad looking. FINALLY. I lost my key. When the electric opener failed, I could not get in and LEER would not respond to my requests for a new key. What is so hard about that? The people at LEER are at the level of idiots studying hard to be morons. I hope they go out of business. They don't deserve to exist. Everyone associated with the company should be out of a job and homeless, maybe then they will learn about customer support.
