I'm sorry I missed the fact that you have a Coleman AC. Both of my AC units were Dometic. I'm glad I was corrected before you did anything to your unit. My statement concerning the 6 vs the 6E comes from this email (which I guess has been proven incorrect). I will leave the tech questions to those that know in the future.

If you are adding a hardstart to your RV A/C unit, use the SPP6 (no E). The SPP6E is not designed for 120VAC applications, The “E” series is also an instant restart unit, this does not allow the generator sufficient time to rampup to full power. The SPP6 has the preferred PTC relay and allows a longer ramp up time. The SPP6 is rated for 120VAC usage.
Remember for every thousand feet above sea level you generator drops 3% of output. On hotter days the A/C drops in efficiency as well. Check with your A/C manufacturer on the correct generator size for your unit. As far as I know there is not a manufacturer that will reccomend a 2000 watt generator to run a 13,500 BTU A/C unit.
If you have any questions about the SPP6 or any other Supco part, please contact us at 1-800-333-9125 ext. 261 our Tech Support will be glad to assist you.
