We found threads where people were having issues flat towing with front lock-rights... sort of the same reason Adam doesn't like the ratcheting sound of his aussie locker, the lock-right is a more aggressive lunchbox locker that tends to not want to let the wheels slip (hence the loud noises).

Didn't even think about the caster being the issue until that didn't work.... Though it did tow "better", it still would lock up on tighter turns.
