I have seen more improperly installed/adjusted WDH systems than I can count. Most were installed and adjusted by an RV dealership. Most were probably installed by a tech who had no factory or manufacturer training and had no real idea as to the function or operation of a WDH.
The only person with a real vested interest in proper installation and adjustment is the owner/operator. If you don't want the responsibility of proper ownership and usage of your own RV equipment you might think about considering a different hobby. That's just the way it is. RV aren't cars, aren't built like cars, don't have the quality control of cars and would be completely out of most folks financial reach if they were.
