Possible replacement for the A/C

Still checking out options.    Partially because I'm hesitant to buy a window A/C, rip it half apart and then figure out how to mount it on the tongue, I've been considering using a portable unit like the link below.  Only mods needed would be a 4-inch hole in a wall or floor for exhaust and water drain.  I don't think I want to route the exhaust out a window since it couldn't be locked.

The BIG question of course in the confines of a pod (specifically the 171) - where the heck would I put this thing?  It would be easier if there were only 2 of us.  I could replace the table with something smaller and put it between the benches, but we have 4 and most of the time the dinette is in bed mode.  It is about 1 foot by 1 foot by a little over 2 feet high not including the tube coming out of the rear.  One possibility is to place it on the dinette bed during the day, since that is out of the way, then move it to the floor in front of the door overnight.  If we need to go out to grab something we forgot there would be enough room to slide by.  If there is an emergency and everyone needs to pile out fast it could just be shoved out the door.  A pain to move it twice a day, but at just under 50 pounds it would be doable.

Any other suggestions?  Our Dometic dripped inside again this past weekend and it is really ticking me off.

We were very close to buying a icamp camper.  I really liked the way it was built and had many different and neat features.  It did have a Cool Cat 2-in-1 A/C and Heat Pump unit built in.  We went back and forth with a dealer in Pa and NJ but never could pin down a fair price.  My worry was there were very few units imported from China.  I also wanted to buy American.

Not sure of the layout of your Pod, but what if you found a unit short enough to fit in the storage space under your dinette or bed? You could run a duct off the front of it and into the living area, and then cut a hole through the floor for a duct to vent out the heat. The only trouble (other than finding a short enough unit) would be extending the controls into the living area, or finding one with a remote (and possibly extending the IR receiver into the living area).

One more mini-split option I just found which will run on 120 volts.   Not as good SEER rating - 22 - as the Mitsubishi mentioned a few pages back, but the Mitsu needs 240 volts.  I've heard reports that the Sanyo (my first post) is out of production, which was the best 120 volt option.

An additional note about the mini-split I just posted about, while its SEER rating is worse than the Mitsu, it is far better than the Sanyo from my very first post on this thread.  So an advantage if you don't want to tie yourself to 50 amp big-rig sites all summer which you would need if you installed the Mitsu.

Thinker, the hole used for the roof A/Cs is the same size as the standard roof vents, so it would be easy to swap in a vent to fill the hole.  Not sure I would install an additional fan since the one in the bathroom is more than enough for the pod.
