Replacing Armstrong with Duo-Therm question

[By the Bay]

I've been perusing the archives and recent posts about replacing the A/C unit (1978 Tradewind) and have some questions.

I see that someone (sorry, can't remember who) said that the only A/C today that is equipped with the drip pan to connect with the original hose is the Duo Therm Low Profile Penguin.

Question: so will all the wiring, um, match ok? (not sure the correct way to phrase that) Will it have controls on the inside (up on the ceiling) the way the Armstrong is currently in my trailer? (ie, that it doesn't need to be wired to a wall thermostat or something).

I have another question about the drain hose, but I think I'll start a different thread about that.

I won't be doing the work of replacing the A/C unit myself, but it won't be at an exclusive Airstream place, so I want to just educate myself going into it.

(And, just checking, sounds like Armstrong no longer makes RV A/C units)
