Is it cheaper to use a window unit other 2 rooftops ?
Would it be cheaper go with a window unit or just use the two roof top units already on unit?

The usual 13,500 BTU or 15,000 BTU units are built and engineered for RV use. Bumpy roads, vibrations, voltage variences, exposed to weather, etc.
A window unit is supposed to sit semi-permanently mounted firmly to an window sill that DOESN'T jiggle, bounce, go 60 mph down a road and rattle it's teeth.
Which is going to last longer?
X2...Even with the unit sitting for extended periods it will still sustain damage from transport. Also think about the thermodynamics of a window unit which is designed to deliver a direct blast of air into a room vs a rooftop unit that is designed just for your rv and is already setup for maximum efficency.
