Hey everyone just bought my first truck ever, 2013 crewmax platinum, and wanted to see what people thought was the best bed extender for maximizing space when hauling dirt bikes? Also it has the plastic bed liner, but wanted to see if the non slip spray in liner was the best option for me, especially if my dog is going to ride in the back? Also does anyone have an option on keeping your dog safe in the back from jumping out or falling out? One last question, I have the track system but no cleats to put on it so is there one that is preferred over another? Thanks so much and I have enjoyed reading the topics posted.
