Why is this only 5 1/2 feet long, isn't the truck width about 7 feet wide ?

Standard front rail on a pickup is 66” +/-. I used this product on a Ford F-350 crew cab, the front rail seal has done a great job of preventing water permeation on a commercial topper.

Will this work between the truck bed cover and top of tailgate to keep out water?

I would get the flap seal that is attached to the bottom of the truck bed cover.

I'm going to have a 1\4" gap on the front rail after installing a new tonneau cover. Will this product compress down to that?

It should, that is exactly what I used it for, had a lip on mine too at the front bulkhead that was about 1/4”+|- lowers then the side rails. It filled the gap nicely and keeps wind and the elements from entering the box.
