Hi Anita Rae,
A while ago I recall seeing a European RV AC manufacturer that has
'storage compartment AC' units. I just found it again:

It gives you the knowledge that it is done/is doable. I'd imagine you
could install a small window unit [as is used a lot by forum members] in a
similar manner if you provided the correct sized ducting for the heat
dissipating side of the unit, and perhaps added an additional fan to aid
with that. This'd have the advantage of being built in and the lowest
position possible to help keep the center of gravity low. And the closer
to the center/or towards the axle you could get it - the better.
Here's one of their installation pages:

Here are a couple pics of a 2001 Wilk Topaz Caravan from South Africa
that shows an AC mounted under a front located island bed that is canted
45 degrees into the center of the trailer. I have no idea how it is installed
but it has to be one of the storage compartment type AC units. This is just
to show it is being done.

I just added these last outside shots so you can see how they were able
to cant the bed 45 degrees. I'd venture to say that the design/look of
the Wilk Topaz Pop Top Caravan is probably one that people either love
or hate (!) as it is a bit unusual. I happen to think it is really kool! It
sure isn't a copycat design.
Good luck locating and designing in the AC. I'd say to floor mount it like
the Truma storage compartment ACs are done.
Cheers,
