It's not normally a problem while the camper is in service, unless you don't have something maintaining the batteries and you are placing a heavy load on them. In this case the problem arose after the blowout.
Many folks will put a battery cutoff switch in the system, so they can eliminate the parasitic draw when the camper is in storage. Personally I keep my batteries maintained and in the trailer ready to go anytime we get the urge.
Speaking of maintaining the batteries, I found that I had a problem with in my truck and I don't know how long it was going on. The fuse that safe guards on the 12V constant power leg of the trailer plug had blown.
I only learned this when I upgraded the trailer to disk brakes, the batteries were disconnected so to test the system and bleed the brakes I plugged the trailer into the truck. The problem only showed because the brake actuator needs a constant 12V power sully from the tow vehicle.
All the other things lights, turn signals and brake lights worked fine and the solar was keeping the batteries charged.
Of course my Ram has one of them square fuses that I didn't have a spare for. So find which fuse is charging the batteries as you are towing and make sure you have spares. You might get a surprise, I have heard of trucks with the tow package, but that fuse is not installed at the factory.
I now pop open the fuse panel and check that fuse during my pre-trip each morning.
