It hasn't been covered since last September. The cover collects water in the back (it's waterproof) and makes a lake, when it is raining. I have been wanting a Peragon bed cover (like I had on my Silverado). One I get that, I can use the cover again and not have to worry about lakes in the bed of it.
And yes, I will be using it all the time. Now that it sits in the driveway 90% of the time, it gets covered in jet fuel within a week of washing it.
