Mine took an acorn from an oak tree sometime during the last week that punched through the UV faded outer dome.
Pictures show the repair progression of "Oh crap, there's a hole in the roof" to
"Fix it with I got at the campground" (ziploc bag and painters tape, got rained on and made it home intact!) to
"Fix it better at home" (slapped a patch of eternabond on there, rest of the roll now lives in the coach for future emergencies)
and now I'm at "Replace it someday".
The OEM dome is about 6.5" high although peeking in through the hole punched I can see a solid 1-1.5" between the top of the inner dome and the outer one so it doesn't have to be that
RecPro has one that is a little taller than average at 4.5" but I think it might have too much of a curve near the ends. The OEM inner is a rectangle that sticks straight up so it looks like it'd interfere.
Elk Mountain has a boxier looking one that looks really close but can't tell on the height if it'd be too short still.
also found another one from them that's on Amazon but not their site. Not sure if it's just a smoke version of the one above
Anyone tried any of these specifically and found them to fit/not fit?
I emailed Elk Mountain for a height measurement since that looks most promising.
@Ray&ReginaD would you mind sharing the part number and how much the OEM cover ended up costing? I have a feeling it's more than I want to spend on the problem but not seeing many other aftermarket options.
Worst case I'll live with my redneck patch until it's time to sell, then swap both parts out for a shorter set like others did.
