Most likely the cause of your problems is a weak connection somewhere. Normally #12 would handle the load with no problem, but if you have a weak connection it's like putting on a hidden load that will get worse and worse as it weakens and causes the amps in the circuit to climb and the voltage to drop.
The best way to check this is putting in an ammeter, and turning stuff on to see if the meter reading really matches the load. Chances are, it's where the loads come together, and it's often the negative return wire because that carries all the load back to the battery.
It's an easy test to use your long jumper cables, and bring a good solid connection on both the negative and positive lines back to where you connect in the camper. You might find that one or the other really helps and then that will lead to the problem wire.
