Furnace filter, cabin air filter - ACE 30.1 2016

I've replaced - and needed to! - the filter in the roof air several times, but I've never replaced either the furnace air filter or the "cabin air filter" for what blows out of the dash.

For turnace air filter (there is one, yes, please?) where is it? How do I get to it. Anybody know what the replacement is? The logical place is at the cold air return, which on my coach is beneath the forward drawers (under the counter area) in the bedroom. But it doesn't look like it's there, and it doesn't look like there's any way to get in there.

For the cabin air filter, some people say there isn't any but other people have posted photos as well as posting about how difficult - or not - the replacement was. Trouble is, I couldn't tell where the photos were even looking from, from under the hood or looking from inside the coach with the doghouse removed. Nor were I sure that the photos were from the same model and year as I have. So, does anybbody know for sure where the cabin air filter is on a 2016 ACE, and how to get at it? OK, I may as well ask... know what the filter is?

I can't say for a 2016, but my 2013 ACE has no furnace filter (air return is same as your description) and I would be surprised if there was any dash cabin filter......I doubt my coach has one at least. The one filter that is fun to change though is the engine air filter. Search the forum for that.....I discovered the secret handshake for that many years ago.
