Every DU-HA is custom designed to fit a particular model of truck. The Chevy/GMC Regular Cab (Classic) DU-HA is designed to fit behind your pre-existing seats and will still allow your seats to fully recline and slide all the way back. It's constructed from heavy duty polyethylene and comes with a lifetime warranty. This model will hold 2 rifles or shotguns, both with scopes, but does not act as a legal gun case in states with gun case laws, unless guns are first placed in gun sleeves.
