2013 Georgetown 378 XL roof caps

[lesteele]

There are 3 caps on the roof that state "pull to open for 1" to 2 3/8"OD pipe. What are these for? 1 is over bedroom, 1 is over driver area and 1 is over the bathroom.

The roof cap closest to your bathroom is probably the vent cap for your black tank/sewer system. You need air behind water to work properly.

On our model, the vent cap closest to the front (over the passenger seat) is a dummy cap hiding coax and a 12V wire in case you want to install a rooftop satellite dish.

Not sure what the third one is for on your model. Just open it up and take a look.

I have a 2012 378TS
Like it was said the front right one over the passenger seat is a dummy cover for SAT cable and power.
The other two are for the toilet and the shower.


If you have any more questions about your rig just ask away.

Speaking of those vent caps, do they just pull straight up to get them off? I tried with medium effort to get the cap off the pipe over passenger seat and it seemed to pull up on the front side of the pipe, but seemed stuck on the back side. I didn't want to force it off with too much pressure, afraid I'd break something.

They do not pop off.
You have to remove the sealant and remove the screws that hold it to the roof.

Thanks. I'll take another look. I didn't see any sealant or screws holding the cap to the vent pipe, but it seemed attached someway.

If you have sealant on top of the cap itself there is a recessed Philips screw beneath that sealant (typically off center of the cap) that holds the cap on the vent tube which will allow removing just the cap independently of the entire vent cover.

Haven't picked up our new rig yet (364TS), but somehow I'm planning to run an ethernet drop from the roof to somewhere inside. Not sure yet what the best approach will be. Is that the kind of thing these caps are used for?

You can also just drill a hole in the roof where it comes inside a cabinet and seal with dicor, that's what they did for my sat install so I did not go thru the splitter, directly to the boxes in LR and the BR. No leaks for the past 3 yrs...

Ramair same here. The cables going up those pipe are not the best cable on the planet specially for HD TV. So much better to make a hole and usually the installer will have a special plate to use on top of that hole to help with the sealing process
