There are two complete sets of LATCH connectors for the 1500 rear outboard seats. 

The quad cab model has a tether on the rear center seat, and the crew cab model has a full set of upper and lower tethers.

.The Insurance Institute for Highway Safety has given Quad Cab's LATCH

 system the second highest rating for its ease of use. 

 Keep in mind that finding a tether anchor can be difficult.

The crew cab's LATCH system received Land's second lowest rating because it's difficult to find a tether

 and can be confused with other seat hardware. 

Also, the fixation at the bottom of the central seat is too low for the seat.
