Yes it can be confusing. Your 50A shore power actually supplies 100A @ 120V. The 50A rating is at 240V. Either way the shore power is outputting 12,000 VoltAmps of Power. The 5500 generator is rated at 5,500 VoltAmps, so it is providing a little less than half of what your shore power provides.
To make it even more confusing your trailer has two AC branch panels wired approximately as shown below. This is why I suggested you contact an RV or Marine electrician.
