How easy is it to remove the Tuff Tonno cover?
The vinyl cover can be rolled up at the cab and secured with the Velcro straps under the cab rail. You can simply remove the cab rail to fully remove the cover from the bed.
Will the Tuff Tonno work with a drop in bed liner that goes over the bed rails?
Yes. If the liner attaches over the side of the bed, you will need to notch the liner to accommodate the clamps. The clamps must be flush against the metal of the truck.
I live in a region that gets a lot of heavy snow. Will Tuff Tonno hold the snow without bending or stretching?
Yes, however we recommend that you remove the snow from your tonneau just as often as you remove the snow from your windshield.
