I have a portable AC/heat pump that I use. These portable units come in single hose and double hose.

I chose the single hose unit because I use it primarily in the Winter and I did not want to suck in cold outside air.

So you continuously "exhaust" conditioned, A/C cooled airflow instead bringing in HOT outside air for the condenser cycle.
COOL...

Mine is a 120 volt, 11,000 BTU AC unit and a 9500 BTU heat pump and it works fine and draws a lot less power than the roof top units do. The vents hoses come with adapters to run out the window but you will probably have to also make a filler piece so that you do not get a leak if it is raining. My unit weighs about 65 pounds and is on wheels so you will have to find a location to store it while on the road. Noise wise the portable unit is no louder than my roof top units.
Obviously a more powerful AC unit will weigh more than mine and may need a dedicated power source.

Costco has a portable A/C heat pump for $389.00

Some of these require a condensate removal method.

With the heat pump, if I pulled in outside air, at zero degrees, NO heat pump, roof top or portable, would work, period. Since I am recirculating inside air at 70+ degrees, through my unit, the heat pump continues to heat the air and to operate just fine when other RV's have to use their LP furnace. Since I like to travel in the Winter, in cold temps, this was important.
Now when I use the AC for cooling, I again recirculate the inside air instead of sucking in HOTTER outside air. Exactly the same thing that you do when you put your dash AC on MAX cool.
The two hose systems use two different fans, one to suck in outside air, and the other fan to blow air over the coil to cool or heat it.
They use more electricity, and from my own experience in extremely HOT and COLD temperatures do not work as well as the single hose system. Here is a link to explain the differences: Portable AC units
