I carpooled today so I don't have access to my bed. Will somebody post the distance from the front of the bed floor to the front of the wheel well humps and the inside width of the bed at the very front.

This is for a 2006 Megacab

 

I had a minute, so I ran out. My truck has the Dodge bedliner in it, so I just measure however the 18" ruler laid in the bed. The hump also has a little lip in front of it, so I measure in front of that.

15" to the front of the hump lip

~ 62" in between the tie down clamps (at the bed level, not the top).

Dislaimer: As you can see, I used an 18" ruler because I don't have a tape measure here. Therefore, measurements are rough estimates. Should be enough for you to size up a truck box... if that is what you are doing.

 

You're a lifesaver TRC51!!!

Good call on sizing up the box. It's actually an auxiliary tank.

Thanks a ton.
