My AC was not doing the job, even with PUGs. I came across this mod in another forum and tried it. It worked great and looks factory installed. I have a dometic a/c and the vent used in the mod was too deep for my unit. I used an inspection/maintenance port with a removable insert normally used on boats (Amazon). It works great. The increase in air flow and cooling is amazing. Great for quick cool down and leave it open for those really hot days. This port works well but it is not directional like the one in the link. Blows straight down and you cannot sit under it without freezing. Here is the link: Coleman/Mach AC Mods - iRV2 Forums Hope it is of some use to others.
