I just bought and installed a hard cover from Rough Country. Pretty happy with it and it was a pretty quick and easy install.

Hard Flush Tri Fold Bd Cover | 5 Ft | Cargo Mgmt | Nissan Frontier (05-22) | Rough Country

They've also got a soft cover if you'd prefer that?

Bed Cover | Tri Fold | Soft | 5 Ft Bed | Nissan Frontier (05-22) | Rough Country

Good luck with whatever you choose!

 

I got this and it works great:

I would go with what design for your year, make and model of your truck. To ensure a perfect fit and install. I also have the S trim. I also have the Gator Sfx Tri Fold. Works really well. Fit perfectly. Easy install too.

 

I got the RHR XL rollup cover from RHRSwag for about $370. It's actually made by Access but sold under the RHR name. Excellent product.

 

I have the BakFlip hard cover on my 6 ft bed. It is really nice. Flush mount and good looking. You can also ride with it up like this and have access to the whole bed
