Outstanding Product and Customer Services from Torneau

Relatively easy installation. We love in Florida and no sign of leakage. Excellent customer service from With drop in bed liner no need for foam stripping. Instructions were specific to my 2024 Toyota Tundra. Excellent installation video from RealTruck

The BackFlip MX4 is the best solid fold cover on the market

Very nice cover

Great looking cover. Well made and fits nice. I liked the rail clamps better on the Undercover flex I had before. Also, I’m not super excited about the cover leaning against the truck when it’s propped up, it came with some foam pads to protect the truck but there are better ways to design the props.


Great Product and service.

Bed cover

I had one of these backflips on my 21 1500 Silverado and it was great so when I upgraded and got my 24 Silverado 3500 I ordered one for it also and I love it
