Hey guys I'm new to the forum, I've got a chevy 2012 silverado long bed extended cab. Currently I'm using an in bed tool box, the kind that fits inside the bed rails of the truck and I'm looking for a bed cover. I'm having a hard time finding one that will fit with my tool box since it runs almost the full width of the bed (0.75 inches clearance on either side leaving out most soft tonneau cover like Truxedo, extang, access etc.). My toolbox does not reach the full height of the bed rails and extends 18.5 inches down the length of the bed. I'm not looking for a solid one piece cover because i tend to haul taller objects. It seems like my best options are a trifold of some kind or possibly a diamondback cover (which is currently my favorite and looks like it might work). Any thoughts on the best type of cover?
