Hello Dave,

Welcome to etrailer, I'm glad you found us!

Looks like you already found the right one. For the Heng's 122112 roof vent on your 2011 Sunseeker, the direct replacement is the Ventline Replacement Dome Assembly # BV0554-01 if you're looking for a white cover, or # BV0554-03 if you'd prefer a smoke-colored cover. Both are designed to fit the Heng's 122112 vent with the continuous metal hinge. I attached an image of the dimensions as well.

Replacing the cover is a straightforward job. You'll simply remove the old hinge pin, slide the damaged cover out, and install the new one in its place.

Are you looking to replace it with another white cover, or are you thinking about switching to the smoke-colored version? Getting things geared up for the next great adventure, where are you headed to next?

Bought mine few years back to go on my 1998 wells cargo 24 ft car hauler. Perfect fit but the price sure has gone up since. Though my experience with e-trailer has been few, I thought their service was top shelf. Just don’t try to get in touch with wells cargo people for help on parts for their trailers, very poor.

@Glenn Thanks for the response Glenn. It would be nice is we could freeze prices, but that is how how our world likes to operate. Raise the prices, raise the minimum wage to catch up, only to raise more prices, then have to raise peoples pay.... and so on, and so on. Let's just freeze the price and the pay and quit the viscous cycle.... my thoughts anyway =)

I purchased these a year ago. they were easy install and worked perfectly. Etrailer has always been the best source for me for these types of products and others.

I replaced 4 domes on my Weekend Warrior Toy-hauler, the old style replacement domes were a perfect fit. I was happy to find the domes available. The installation was fairly simple, the first one was a learning curve
