Ok... I'll throw in a stupid question.... Is it possible that when you are traveling down the road, that leakage on the genny door seals would disrupt or negate the blower air flow.. or perhaps pressure from under the coach negates the blower pressure to some extent reducing airflow thru the radiator? In air cooled aircraft engines we are looking for a negative air pressure downstream in order to receive max airflow .. you can use two gauges to measure the differental pressure...
