Yes, that is an EMS. It monitors how much power is available coming in, and will turn off high load items like ac's, water heaters, sometimes the microwave, mine will also shut down the refrigerator. If you are on 15, 20 or 30 amp it monitors the available power and shuts it down.
What doesn't make any sense is that it would go somewhere in the front. On my distribution panel, the power comes into the main double 50 amp breaker, that panel has the large load items and a 30 amp breaker that goes out to the inverter/charger, passes through and come back into a sub panel with a 30 amp breaker and then all the outlet breakers are fed off the sub panel.
What it does in simple terms, is turn relays on or off when your power is limited and you exceed the load the incoming power can supply.
Look again, or better yet take some pictures. Since you have one labeled main and and it is at the foot of the bed, that is your main power coming from your ATS. I can't imagine Fleetwood would run power all the way from the back to the front for a subpanel, but I've seen some weird things in RVs.
The intellect EMS you are describing is not made anymore but there are distribution panels that can replace it.
