It depends if you plan on putting your AC inside the tent or outside the tent and if you’re worried about smell. If you put a portable AC in your tent the discharge of hot air will have smell. If you were cooling the room the tent is in with a portable AC and are using a charcoal or carbon filter then you’re fine.Ideal air makes a dual duct portable AC one for intake and one for exhaust these guarantee that no smell leak though I have experienced they leak smell a little.PS there is a difference between portable AC units and window AC units window AC units do not leak smell they cool the air that is inside the room and use air from outside to cool the unit. Also 87° is too hot you risk having something called Fox tailing.
