OK i just bought 2 trailer houses for $250, and since all i have is lean to's, i figured i would make one in to a cooler room, and a place for grooming chutes and stuff, and then the other will be used for pigs, but i was wondering what i should do to the traielr house so i can make it into a cooler room? I am going to gut it all out, and then cover all the windows, but what else should i do??? ))
