Been thinking about certain things to make the blazer a more comfortable rig while out exploring. One has anyone every add a rear ac unit to the k5? either a custom one thats out from like the center console or even fit a rear unit from a blazer? Has anyone made a custom cabin air filter for these old rigs? Driving behind other rigs in the dirt with the ac brings in a lot of dust. Also has anyone converted the top to a flip top tent or a half flip top deal? I know roof top tent are all the rage these days but it created a higher center of gravity and has the chance of getting caught on trees and what not.
