## Questions & Answers

**Q: Does it fit a chevy truck? All I see is ford**
A: The BAK BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover you mentioned, with part number 448339, is specifically listed as fitting the 2021 - 2023 Ford F-150 models with a 5' 7" bed.

Based on the information provided, it appears that this particular tonneau cover is designed and intended for Ford F-150 trucks, and there is no indication of it being compatible with Chevy trucks.

If you are looking for a tonneau cover for your Chevy truck, I would recommend looking for options specifically designed to fit your Chevy model and bed size. It's important to ensure that the tonneau cover you choose is compatible with the specific make, model, and bed size of your truck to ensure proper fitment and functionality.

**Q: where is the part number located.? I don’t see no white sticker on bottom and no box**
A: I can't help you.  I got a Bak Flip G2.

**Q: How durable is the MX4? Read many reviews of this tonneau cover denting easily.**
A: Its as tough as they come. I've had my 4 year old nephew standing on it and no flex at all. Plus its so easy to install and operate, hell my wife finds it easy to use. Its made with top notch materials and looks great on the truck. I had friends see mine and bought one just from sight. we love ours and have no issues with it at all. 
Its a solid buy!!

**Q: Will this fit a 2023 f150**
A: With a New Model Year F-150 it would be best to contact the manufacturer directly. Although they do reference it fitting 2021-2023. Mine is an Older Model and it fit correctly.
