3.2 cu. ft. fridge is perfect, it can be shared with two people too, unless you have alot of food for yourself.
there should be room for it but if you're in a triple maybe you can contact your other roommates to see if they are bringing too. if they are, then your room might just have less spaces and might get hotter from the heat. if you can, talk to your roommates. some people have their contacts shown in the roommate list.
i wonder why no more fridges for triple rooms. that sucks... what did they do with all those fridges from before.. so werid. :(
