Typically the requirement to disconnect the battery is from the manufacturer but I looked through the owner's manual for both the 2021 and 2022 models and they don't list anything about disconnecting it under the recreational vehicle towing section. Roadmaster, one of our suppliers, does has a note saying that the battery should be disconnected with part # RM-766 to flat tow and that there could possibly be more than one battery in the vehicle that will need to be disconnected. I've never run into a situation where the vehicle manufacturer didn't list the requirement so you may have a legal case if they won't warranty the damage.
The tow bar wiring is powered directly by the motorhome's 7-way and would have absolutely zero connection to the brakes on the vehicle. The dealership is just trying to pass the blame. The supplemental braking system could potentially lock the brakes up but you would've had to have installed it incorrectly for it to malfunction. Check your wiring and ensure there's nothing wrong with your breakaway switch. It's much more likely that the battery be connected activated something within the vehicle, like an anti-theft system, and activated the brakes.
