This is where you need to do troubleshooting with a voltmeter. If you are comfortable troubleshooting live 120/240 vac power, then use a voltmeter to measure across the two load side terminals of the main 50 amp circuit breaker. It should show 240 vac. If it shows 240 vac, then your hots are good. If it doesn't show 240 vac then you are missing at least one hot.

If it doesn't show 240 vac, then put one meter lead on one of the 50 amp breaker load side terminals and the other meter lead on the neutral buss bar. It should read 120 vac. If it doesn't show 120 vac, then that side is missing its hot connection.

If it does show 120 vac, then move the meter lead to the other terminal on that breaker. If it doesn't show 120 vac, then that side is missing its hot connection.

This will show for sure that you are, or are not, missing one hot leg to your main breaker.

I don't know the routing of the wiring from the rear connector to the circuit breaker panel, but pulling 3 feet of wire out the back, it is possible you pulled one of the wires out of the main breaker panel.

If you are not comfortable troubleshooting live ac voltage, then by all means call a mobile RV repairman. Be safe!
