Length of a 2015 trd

Trying to transport a couch that is 7.6FT was wondering how long the bed is with the tailgate down

 

Short bed is 5', long bed is 6'. Tailgate down adds about a foot extra.

 

Drop the tailgate, put couch in bed, use tie-down to keep couch in bed, don't worry about the foot or so of couch hanging over the end of the tailgate.

I put 8ft lumber in the bed of my DCSB all the time. About 2ft hangs past the tailgate.

 

Thank y'all so much!
