I know that is probably part of their issue. We have the setting at 30 i believe, may have even put it to 50 now. Every item in the truck has been swapped out. We even put new sensor harnesses in Friday. They don't have assigned batteries, so there's no telling which is causing the most issue. And they are to cheep to replace their 13 year old, yes 13 year old, batteries. The last battery in it read 70% charged when they claimed to have issue. It was at 24.7 volts dropping to 23.2 while traveling.
