Two honda generators in tandem

Thank you JD - i wouldnt know the first thing about hooking up an aplianceair or micro-air. I cant even get on to roof of trailor. Shouldnt 4200 watts be plenty? But altitude might be the point of all this? What size gen do i really need in colorado? 5000, 6000, 7000 watts for a little a.c. or is something just wrong - frustrated cuz i have 2200 dollars invested in gens and still not working.
