They have a site built home with a basement. Furnace and duct work is in the basement so heat lost from the ducting is not actually lost.
Yes, mobile home units can be more expensive - just like everything mobile home or RV specific.

Got it! So a 40-50,000 BTU at 95% would hopefully be less than $10,000, even though it is for a mobile home. I was told it shouldn't be above $7,000 for me by that HVAC tech who works in Colorado. He didn't say if that's with some sort of credit or utility rebate or not. Just to expect $5,000 to $7,000, and not more than $7,000.

When I was giving prices I was talking installed for the forced air heat pump.

What did I say that sounded like it wasn't ducted? It is ducted, with 6 floor vents (actually 5 now since we covered one to put the frige over it) that blow heat out. They are about 8.5 x 4" in size. The duct goes along under the trailer with the furnace in the middle.

If I had one installed I'd probably just go with whatever the installer offers. I have no idea what the unit price would be through an installer, just that it's no more than $7,000 for a gas unit installed.
If I go with a heat pump I think I'd go the DIY route: I'd put in my own 240V line and install it myself. I can just take the one that I installed for the 40A EVSE that was at the front door. It's plenty long, all I'd have to do is cut it as it goes right by the furnace under the floor.

Interesting. That makes for a lot of unknowns. Like, where is the exterior unit going to go? What does the extra refrigerant cost?

Yeah. It's sounding more and more like I should just ask an installer what is best and go with that option.
This is my exact unit I currently have (Coleman 7663):
