I dig my Mountain Hatch a lot actually. I didn't pay $255 for it as it must have been cheaper when I bought, but it's been worth it in my eyes. I have the earlier version without the cupholders on it and supposedly it's a slicker texture than the new ones.
Honestly the thing is pretty awesome. The regular tailgate drop down sucks for camping and every day use, the Mountain Hatch makes the tailgate so much more functional. Yes it's a flat piece of plastic, but it's a been a killer upgrade for us. It's food grade if you need to cut on it, textured to keep things from sliding, lightweight, and cut for a perfect fit. Plus I don't have a garage with a work bench so my tailgate doubles as that now. The hatch actually makes the whole tailgate seal tighter, so along with the lower seal I installed between the edge of the gate and the bed I get less dust in the back of my bed compared to what I got before I installed all of it. I still get dust back there, but it's definitely less. I will say it can be a bit slick in rain or icy weather if you stand on it.
I'm sure if someone wanted to they could go and cut out something that would fit the same, and maybe be a better end result, but this thing has been pretty bomb for us and all I had to do was place an order. I'm happy with it.
General disclaimer, Mountain Hatch works with the charity fundraiser I'm doing. They've gone out of their way and offered to support what we're doing for a charity I care about. I've met them in person and they are good people. However while I may be thankful to them, that doesn't change my opinion of their product.
