Just thought I would share an awesome interior upgrade I did in my 12 valve. I LOVE my 12 valve but the interiors in these trucks are pretty dated. I installed a pioneer DMH-WT 8600NEX and LOVE it! It has apple and android CarPlay and tons of other awesome features. I installed an alpine High resolution backup cam and will be installing another one on the back of my cargo trailer as well. This thing even has Amazon Alexa capability. I installed a killer stereo and did a TON of sound proofing on all interior panels. I actually installed 2 layers of dynamat everywhere and then a layer of memory foam carpet padding over that. For a 12v, it is really quiet in the cab
