Hi, new to the forum. I have converted an 86 Chev G30 mini school bus into a camper, and i have mounted a Danby 5.1 "window shaker" air conditioning unit into a plenum, which creates the equivalent of...

If you already have all the components, then give it a try. Using short leads, connect inverter to chassis battery. Monitor chassis battery voltage while you're driving with A/C on. If voltage drops below 13.0V then alternator is not big enough to power A/C.

i do not have the components as of yet. i was hoping to know for sure if the idea was even feasible before i buy another inverter. canadian tire has a 1000w pure sine wave on sale this week for $190.
i am willing to spend the money on the components; including a higher output alternator and better battery, if necessary; if it means not significantly reducing the lifespan of my house batteries. it would appear the idea is feasible, but now i need to decide on the best way of doing it. house batteries vs. starter battery?
i might be best to buy the other inverter, and keep it as a back up if nothing else? but i like your idea of doing a trial run... at least i'll know where i stand with the existing equipment. my hope is the alternator is already a high output, seeing as it's a bus. thanks!
