midi heki replacement for a 2012 Lance 855S camper

[Ski_Pro_3]

I have a 2012 Lance 855S camper with the bed roof hatch completely destroyed by a wind storm. Pieces were scattered to the 4 corners of the earth.
So I'm looking for a replacement, but having a tough time finding one. Can anyone suggest where I might find one? Perhaps another brand or aftermarket that will fit? I found this on eBay and would like to give it a go, but only if others can endorse it as a viable alternative to the OEM one on there now.
Thanks in advance!

It would be a good time to see if you can find a marine hatch close to that size which might be more durable?

Lance dealer? rvpartscenter.com could probably help you out.

I found this same hatch for a lower price on Walmart's website.
I think I need the 700mm x 500mm size but unsure as I have not had enough dry weather to take the old one off just yet.
