Hi there, are you my driver from Uber? I hope not because I am managing the small business of Uber-like taxi company and we use Contractor Scheduling Software to schedule their time. This system computes the amount of time spent for safe driving as well as regular vehicle check ups and those who do it on time, normally waste less time on repairs and inquiries. And of course they get bonuses for that.
I'm guessing 30 amp RV service. You can't run both air's at the same time. Both A/C's draw too much current. Your EMS is not a true EMS. It is a "Load shedding system" It senses high amperage and removes an assigned load for a period of time until the required load gets down to the 30 amp level.
If you have proper voltage at the campground, the refrigerator is on propane, the water heater is on propane and the batteries are at least 90% charged, you coach will run both air conditioners at the same time.
If you have 30 amp the EMS will not allow both acs at same time if there is any other load. Also depends on size of acs. If both try to start compressers at same time overload possible. Brand new may work but as acs age they tend to pull more imo
Those older Fleetwoods have 11k. Why do you need to run by itself or even both together? I was also choosing the system for my car a few years ago. When I needed help with coursework on air-conditioning I was stuck with the problem of what system to choose as an example of my study. Luckily I found the best choice there
