- Written, Step-by-Step Instructions for Measuring Your Truck Bed for a Tool Box or Transfer Tank
- Step 1: Start by Measuring the Exterior Bed Rail Width — From A to B
- Step 2: Measure the Interior Wheel Well Rail Width — From C to D
- Step 3: For Transfer Tank Fitment, Measure the Wheel Well Width — From E to F
- Step 4: Measure the Vertical Bed Depth — From G to H
- Step 5: Measure the Length from the Forward Bulkhead to the Wheel Well Hump — From I to K
- Step 6: For Towing Applications, Measure the Length from the Forward Bulkhead to Tow Hitch — From I to J (Optional)
- Finally, You're Ready to Make Your Purchase & Install Your Truck Bed Tool Box or Transfer Tank
the bed closest to the truck cab.
This measurement is important as you will need to ensure that your tool box or transfer tank
does not interfere with your trailer hitch when towing. This is especially important in short-cab
trucks.
In order to measure correctly, grab a lengthy 2x4, a pole or a long straight edge of any kind.
Place it over the 5th wheel rail closest to the truck cab or on the outer edge of the gooseneck
ball hole, on the side closest to the truck cab, allowing it to span across the bed rails.
Following the bed rails, measure all the way from the truck cab to the 2x4 or straight edge,
which should be placed over the forwardmost 5th wheel rail or the forwardmost edge of the
gooseneck ball hole.
This measurement will give you the distance from the truck cab to the front 5th wheel rail or
gooseneck ball hole. Make sure your tape measure is straight and not sagging when taking the
measurement.
This measurement will be notated as "length from bulkhead to hitch." Record this number.
In the example above, the distance, from I to J, to the gooseneck ball hitch is 37.25".
Next, Double Check Your Measurements for Accuracy
Once you have finished measuring and recording the numbers, measure once again to ensure
the correct measurements were made.
Your numbers should look like the example below. (Note: these numbers are used for
example only.)
Measurement 1: Exterior bed rail width — 72.75"
Measurement 2: Interior bed rail width — 65"
Measurement 3: Wheel well width — 51" (for transfer tanks only)
