The cab air filtration system for the A/C system (it is an option over and above the standard A/C system) will pressurize the cab. As for the backup camera, that would have to be sourced locally, perhaps a camper supply company. Hope that helps.

I may have to look into a backup camera for myself. I am really tired of trees jumping in behind me when I'm not looking and sometimes even when I am looking.
