On this trip we have encountered rain, some heavy and had a leak dripping on the dash coming from what appeared to be a windshield leak. Can't tell exactly where with the front cabinets and interior trim, but a couple spots in the center and near the right edge. I also know water can travel "miles" before showing it's face. But after a night rain and small leak, we drove the next day several hours in sometimes heavy rain and NO leaks. My original suspicion was the windshield seal but now I'm not sure. Before the trip I inspected the roof and sealing surfaces and a quick check all looked good. Items on the roof up front that I need to recheck are the front cap to roof seal, sealing and mounting of the spotlight and the Weingard satellite receiver, and around the door.

If anyone has any other suggestion I'm all ears. I'd rather not disassemble the front interior if at all possible. No staining or leak evidence anywhere except dripping on the dash when not moving.

MARKER LIGHTS on top

Yes I'll check those also but I would think that they would be vulnerable while driving. Leaks, like electrical, can be tricky and elusive.

x2 on the marker lights. I had the same problem with my '06 Itasca and it turned out be the marker lights. Sealed around all of them and no further leaks.

Get outside with a water hose and someone on the inside. Keep the hose aimed at suspect areas until the leak shows up again. Chuck

I know this a different maker but mine only leaked when stopped. Found the sealant on the cap edges was not that good. In fact I could lift the edges up. And what I found out the water was running down the gutters like a water hose and mad it's way to the windshield. After sealing no more leaks. I know I will get beaten up because mine is a Winnebago Sightseer but this is what I have found on friends class a.

Okay, just a thought. Since it leaked the first time, but not the 2nd time, even though the 2nd time was in heavy rain . . . . did you by any chance have the dash AC on the first time, and NOT the 2nd time? Maybe the water was dash AC condensation, and not from outside at all. I will sometimes have this happen when I am running the dash AC for extended periods while driving in our coach. I still need to chase the actual drip, but it drips on my feet, and it IS the dash AC. Just a thought.

I had a "leak" drip down from the cabinet over the dash that I determined to be condIensation inside the fiberglass front cap. If you have high humidity, cold outside temp and warm inside the coach it could happen.

The leak occurred during 3 rain showers/storms sitting static, as in overnight. When driving there was no leak even in torrential rain. One of the rains was light but the wind was blowing aft to front. I am suspecting the cap/roof seam and will inspect everything including the marker lights, next week. Will be home tomorrow and parked under a barn. Johndale's picture is what I suspect.

Hey, goof on my part, I re-read the OP's post. I had misunderstood and thought the water was leaking UNDER the dash, not ON the dash, so my AC suggestion is not applicable. Hope you get the problem fixed! Take care,

I've replaced two marker light lenses in the 5 1/2 years we've been on the road because of hairline cracks. Cracks which are hard to see from ground level. Even had caulk kind of pull away from around the lenses causing a leak. Don't forget to put a glob of caulk over the screws if you have to replace a lens.

Well last night at Winstar Casino it poured swimming pools and wind around 60 mph. I pulled in slide before it hit so I wouldn't loose my cover over the slide. Didn't sleep to good because of the rocking. It reminded me of my wedding night but DW was curled up in a ball with blanket over her head. Checked out the RV this morning and no damage and the best thing NO WATER leaks. We had heavy rain before but not like this. So I feel good on my fixes for the leaks. But now DW wants to stay another night to donate her money. She was up $300 but walked away with a $12 profit. Today I feel a negative day for her but oh well she brought what she wanted to leave here.

When my HR was made (2006 model), HR did not use sealant to mount the 1-piece windshield, just the gasket. With the 3-pt leveling system the glass can and does move around. Sometimes I have a gap, sometimes I don't. Also depends on the temp and direct sunlight as to if the gasket seals or not. I just toss a towel on the dash. A PITA, I know but I've heard stories of sealing the window and then they crack.
