Ford's design in the 2015/2016 F150 CrewCab was the installation of the tire blocker,this was not installed on 2015 REG/EXTCAB F150.Ram was allow not to be tested because of the 2016 IIHS critiera back in 2015 meaning they were changing the offset impact,RAM engineering under my understanding change some of the structure on trucks built after July 2015,to improved the new parital offset crash test for IIHS.In the 2016 IIHS crash test it shows clearly the tire collasping the firewall and pushing up against the lower part of the legs hence trapping the driver,this could lead to lost of life if their were a fire and no rescue on scene,unless others were able to pull the driver to safety.I feel that FCA simply can not give a blanket statement saying ""all our cars and trucks,suv meet Federal/State guidelines".This does not help insure consumer confidence in RAM products they must do more by starting a campaign to show/prove with there internal documents and internal crash test videos proving be on a doubt that the RAM 1500 is a very safe truck,but with a IIHS rating of poor on structual,and marginal on roof, I find they have a up hill battle.This RAM 1500 1/2 TON either in a CREW or Quad structurally is not sound "Marginal" on OVERALL,and "POOR" on structure and safety cage on a 2015/2016 built after the design changes with into effect on the warren line,is bad,some were RAM engineering really needs to come forward on this because it reflects a lack of sound engineering,or being pressure to just get by untill the next generation RAM 1500 appears for testing.Mr.Manley who now heads up RAM,as well as Jeep,appears to be a sitting duck...
