In the new Bighorn it appears that both are fully ducted and both do not have the ceiling plate, but rather remotely placed air returns. We have a PT Crusader that has for the main air and it's much quieter than the type with a ceiling box return. Assuming that both airs are that way, how long has Bighorn been doing that? I am going to research used models and need to know what to expect. If I see a model online that interests me IF the pictures include the ceiling I can tell but often pictures don't show that. Thinking the 3160 model as it's a length and weight we want.
Thanks
