Step 4. Make sure the wheel well humps will not interfere with the tool
box body.
In this example, the tool box lid depth is 20" and a piece of tape was placed on the truck bed
rail 20" from the bulkhead (see the video above for guidance).
Next, notice the tool box body depth is 11.75". Measuring downwards from the tape, see how
much depth there is available over the wheel well humps.
In this example: 14" – 11.75" = 2.25".
You will need 1" of clearance to ensure the tool box will not rub. If the tool box depth is within
1" of the wheel well humps, the tool box may not fit properly.
Step 5. For towing with 5th wheel or gooseneck hitches, make sure the tool box is at least 6"
from the 5th wheel frame rail or gooseneck ball hole.
