These tunnel boxes are a good addition to any tow unit for more storage space. They can be used over fuel tanks, battery boxes, or wherever you need to add storage.  Alternatively these boxes would work great as a new build. They feature flat top and bottom and are expertly crafted from 3/16" aluminum with smooth and seamless joints and edges. Stock dimensions are 39" tall and 94-1/4" wide. Other sizes can be made. All boxes are made to order. You can expect a one/four month completion time.

Recommend ordering with shelf kit on all of our tunnel boxes, for better structural stability and more storage options.
