Had a Truxedo Truxsport on last truck and it was great. Looking at one for my new SD but was thinking the lo pro or x15. The x15 is a canvas material. Anyone have experience with canvas over the leather grain style? Is it as waterproof? Im in Pa so it will get snowed on and i dont want whatevers in the bed to get wet. The on top of rail mounted truxsport kept everything bone dry

 

If you're really concerned with the stuff in the bed, I'd look into a hard folding cover. Much more protection, and a lot stronger with snow.
