2500 HD flush BAK flip MX4

The cover came undamaged. Install was about 45 minutes. Works well so far. The people at Tonneau Covered were a pleasure to work with.
Thank You

2nd BAKFlip After 12 years of success

I had a 2012 vintage BAKFlip VP on my F-150 and so far expect that this MX4 on my 2024 Tundra will also serve at least 12 years.

One broken part in shipment is being replaced. Once I get it installed, look for an installation video as many of them are out of date with the new hardware and an initial review. So far 5 Stars and no complaints on the initial purchase and the replacement parts (once they arrive). I don't know why the previous link would not accept my YouTube channel link but it is txw5csm if you want to look it up.

Like Texas and my Amateur Radio call sign of W5CSM.
