f150 6.5 bed, What is the length between tailgate and Wheelhouse @ floor

 

If you have access or own said truck and a tape measure that would work. If not the you probably need to specify the year of the truck so someone with a matching truck and a tape measure can check for you. I have a 2018 supercrew 6.5 and a tape measure but have no idea what year truck you have and if it is different between a supercrew and a supercab you posted.

 

On that chart, measurement "C" is what you need.

 

My 18" Kennedy tool box fits in that space with a few inches to spare

That would give him the full bed length. He only wants from tailgate to wheel well.

 

LOL, yep, you're right. I'm an olde sailor, wheelhouse would be the cab.

Didn't that used to be called "inner wheel well'?

 

I have never heard it called a wheel house.
