This was originally designed for a 2010 model ( stolen....) so I figured what could change in one model year to the box of a pickup truck. I figured wrong. After alot of alterations i got it to fit. Eventually i was able to install my Viair 100% duty cycle compressor and 2.5g tank. Red-top battery and dual battery monitoring system. Squished in an 1800w inverter and an over complicated lock & latch system.
