Two inverters for 50 amp service
We have a Go Power IC Series 3000 watt inverter and 50 amp service on our 5th wheel. I have 2 complaints about it that I wasn't aware of when it was installed. The monitor panel only monitors Line...

The monitor panel only monitors Line 1. The current limit function only limits current on Line 1. So when plugged into a relative's 15 or 20 amp service, we can only see and control what is being drawn on Line 1. And I would like to control the current on both lines so we wouldn't inadvertently trip the breaker feeding the RV.
Yes, you can get a current monitor that will display the current being draw on each leg, if that is what you want. This will NOT solve the problem of tripping a 15A or 20A service feeding your RV. When your RV is hooked to your relative's garage outlet the adapter will only feed 1/2 of your AC breaker box in your RV. That 1/2 can STILL pull 50A !

Is it possible to have two 2000 watt inverters (one on each line)? My dealer says no. But I don't see why not as nothing in the RV runs on 240 volts.
This statement has nothing to do with your first statement. Inverters are feed from batteries, not an outside AC voltage source. (Unless you are going to use an external battery charger connected to your relative's garage outlet. If you do this, you have the water tank problem. Will the incoming water (power from garage outlet) be able to keep up with the outgoing water (power to your RV))

Correct me if I'm wrong, but to create 240 VAC for two 120 VAC lines, the 2 lines have to be out of phase. And if the lines were in phase, 0 VAC would be measured across the 2 lines. So the output of the 2 inverters would be out of phase when plugged into a 50 amp service and in phase when plugged into 30 (or less) amp service. But I don't see an issue with that. Am I missing something?
(240VAC is not 2 phase. It is "split phase", but ...) You are correct ! You can do this but it will not meet any electrical code !
Can You Power a 240 Volt Panel With Two 120 Volt Inverters?
You can do something similar at your relatives house IF you can find another outlet that is on the opposite leg from the breaker panel and you have the correct adapter (likely custom made).
