Is this box lid set forward to allow this box to pushed up tight to another box without the lid hitting the other box?

I have a weather guard box in the front of my bed and want to place another box tight against it in the pictures it's hard to tell if this box will allow that

Can this box be mounted flush against the bed and the lid still open all the way?

Is the lid offset mounted to allow opening when mounted flush against the front bed? Someone else asked the question and you referred a link to pictures but the pics don't include a true side view elevation to answer the question.

The installation instruction say: With the truck on a level surface, place box in truck bed and center. Ensure truck box lid opens without interface. You can contact Customer Care at 888-523-3370 Monday thru Friday from 8:00 AM to 5:00 PM. We can email the installation instructions to you.

Is the 300401-9-01 and the 100401-53-01 able to fit in a 2015 Colorado extended cab? Can my bodyshop purchase it direct from you?

Unfortunately this all purchase chest will not fit with your model of pickup truck. In this case we would recommend the 644 model all purpose chest. This can be purchased through any of our distributors in your area.
