While diagnosing a leak, I discovered a crack in the outer shell of the skylight over the shower. It runs from the base up about 2 inches. I am pretty sure that this is the source of my water incursion.
My question is -- what do I do about it. Replacing the skylight seems like a high buck fix. Can the plastic be repaired? If so, with what?
Thanks!

Whatever you decide, fix it pronto. A fairly large area of sidewall delamination on our old '97 Adventurer was due to a cracked skylight over the shower. The previous owner did a fix but apparently not until after the damage was done.
If you don't want to replace the outer shell, you could certainly put some eternabond tape over the crack....that will keep it from leaking and likely prevent the crack from spreading. Eternabond is good stuff.

A temporary fix is to sand the cracks and then caulk over them with a polyurethane caulking available at Home Depot.
Changing out the outer skylight is not a really big deal. The hard part is getting the old caulk off the screw heads so you can remove them. The new skylight cover is about $150 (for my coach) from Lichtsinn including new caulking. About a 2 hour job.

Replacing it is the only good option. I had one like that in my hallway, and it was about the size you mentioned. By the end of that year it was twice that long due to vibration, temperature change, etc. I sealed it real good with epoxy, and it made a temporary fix, but it still just kept growing. After a second epoxy patch failed, and the crack was halfway across the whole skylite, I gave in and bought a new skylite. No more problems. Just got to go ahead and bite the bullet and do it. Not repairable once the crack begins.

If the coach is not under roof, you need to keep the water out. Drill a small hole at the end of the crack and caulk over the crack and fill the hole until you get a new skylite. Good luck and keep us posted.

I replaced mine to the tune of $170. If I had it to do over again, I would probably cover the crack with Eternabond and keep going. Simple repair...

I replaced mine this summer. I first repaired the crack while I got the replacement outer skylight. Mine happened over the winter and spring thaw allowed water intrusion causing some delamination. When I did pull the old one off, it literally disintegrated. I don't think I would depend on Eternabond, except as a temporary repair until it can be replaced. Mine cost $130 and I picked it up at the Winnebago factory. i used butyl tape as a base to put the skylight on and then covered over with Dicor self leveling caulk.

4 years ago I found a 4" crack in ours. I used polyurethane caulk to fix it thinking I would replace it in a short time. 4 years later and no problems.

New is the answer,i have done quick fix. Fiberglass repair kit will fix the skylight and still let the light in.
Purchase at auto parts or boat store. Do the complete cover, that way it does not look like a patch job. Sand the old skylight cover first.
Good Luck.

On my previous 97 Adventure I had 3 cracks about 2" long up from the base. I also used fiberglass mesh and rosin to cover the cracks after sanding the area. It stooped the cracks, let in light, and never caused any more problems. I never had to change the skylight.

I lived for 3 years with cracks in the corners of the outer shell. The key was to stop the crack from spreading. With the advice of an aviation tech on this forum, I drilled small holes at the apex of each crack to stop the spread, then got a 2 part epoxy from home depot especially for this type of plastic and had no problems till the wind took off my awaning and smashed the thing completely. The replacement was straightforward.

Thanks for all replies. The consensus is 'replace it'.
I have done a temporary fix by caulking it with marine caulk. I am not using it right now so a static fix should hold until I get tne new one.
