Has anyone with fr3 had trouble with water leaking on passengers feet while traveling? Have new fr3 and no leaks while parked but rain stopped and started driving and water started leaking in vicinity of vent(heater outlet} by passengers feet. At first thought it might be splashing up from road and coming thru the doors in heater. later thoughts that it might be a stopped up drain from ac since it was not raining at the time but very humid and warm. Coach is only about 2 months old. any ideas or trouble with this?
