Jon, my 190 drains out of the B in each direction depending on front or back leaning whichever way...... down the drip rail to the front if parked that way.

Seems to me that having to lean one way or the other means something is wrong, needs fixing or park it 'correctly' - a guess.

As does ours. The nearest inside area under that cover is very obviously designed as a "dry" area, I think, as it sure looks that way. The only water that should ever get in there would be from the rear louvers and unless going straight horizontally, if won't get far in. Condensate water should get caught in the tray to a drain hose or channel, IIRC.

So how do you account for the extensive water infiltration before I got it, and zero infiltration afterward? Could the forward drain channels be plugged up? It was parked under large trees and I have found debris in just about every conceivable nook and cranny. A year and several cleanings later I still find crevices I missed...

I haven't been able to open the cover yet. Tried, but the Phillips head screws securing the cover wouldn't budge. I squirted some penetrating oil and left it for another day.

Roadtreks with those style covers and drainage systems have had several different issues over the years that we have heard of. Some of the condensate drain pans had hoses that ran down and out the van at the floor level that got plugged up and held the water back. Others have had stripped screws holding the covers down, or the nuts for those screws not properly sealed to the roof flange that the cover bolts to. Junk, caulking, poor fiberglass work the would prevent water from following the flange to the rear all have showed up.


Not a stellar design, to be sure, and the Roadtrek deteriorating quality over the years certainly didn't help the situations.



From what we have seen, a setup that is properly built and not plugged would have to be very nose down to have that cause a leak in nearly all weather, although severe wind into the rear could make it worse in some cases.


In the case of the OP, the warped cover is certainly going to make it leak as any water on the roof is essentially going in right at the front of that AC cabinet, which is not designed to stop water, as it would be stopped at the roofline.

Luigi / Jon,

Here's some clandestine photos I snapped at the Roadtrek factory in 2011, showing the underside of a 190 roof in process. I would expect the 170 to be similar, but 20" shorter. However, note the "small-ish" opera windows at the front, which apparently came on the scene sometime during the 2007 model year. You may have the earlier/larger windows, in which case I can't vouch for how your roof is built. Anyway, for this late model style roof, you can see that it would take an awful lot of water and nose-down angle to spill over that "dam" from the A/C "box" into the interior. However, I'm not sure how they did any drain line from the front of the A/C area, if there is one. (Last photo is of my 09/10 RT 190P.) Note that the A/C would be bolted down to the (fairly thick, I think) wood embedded in the fiberglass. BTW, the way the A/C cover is built (of thin ABS plastic I think), it is difficult/impossible to draw down the front and sides to be watertight, and there is no gasket.

Regards, Dick

Interesting. About what I was picturing, and you’re right, if that lip is typical, it seems unlikely to spill over. I’m at a loss, but since I’ve been dry, I’ll keep doing what I’ve been doing. And if that changes, I’ll open it up and have a closer look.

Sorry to sorta hijack this thread, and I hope something here helps the OP.

Good job. That's a view not many have seen I bet.

Thank you all for your suggestions. I will for sure be going up a ladder to see if some of the screws look like they have loosened. I also might as suggested take the cover off completely and re-install it. It will for sure be an adventure. Thanks for the pictures of the fiberglass roof. They are very interesting for sure. The information you guys have provided and continue to provide will prove invaluable.

I have an RT 08210P. 1 - I had to replace my TV antenna cable (exterior) and boot. Removed the interior antenna directional crank and found a cable splice above the crank. Was easy to replace the cable from the splice to the top of the antenna and install a new boot. 2 - I have a similar spot on my AC cover, but it's towards the rear on the driver's side. Extra dicor with periodic inspections have solved that issue (during a hard rain in FL one time it did start leaking along the side of one of the interior bottom vents, so that's how I discovered the problem). 3 - I believe the factory did not cover, but I added a Lippert Components 389381 360 Siphon Roof Vent Cap - White (Gen 2) to keep out debris from my neighbor's tree. It's also supposed to help with odor control. Very easy to install and so far has done the job! Good luck!

@rowiebowie
I need to remember that quote:
"If it's already broken, I can't hurt it by working on it" principle.
