Heng's (90008-C1 Opaque White 15" x 22" Vent Lid

It worked great

There were no instructions

Worked great on my toy hauler.

The part fit my 2001 Bigfoot 15C truck camper. The gasket seals too, unlike what another reviewer described. Slide the cover onto the hinge before attaching anything else to it. It is much more translucent than the original cover. I tried to fix that by sliding some reflectix insulation between the hatch and the aluminum support beam. It blocks most of the light and will probably reflect some heat as well.

It's a cheap vent replacement that's meant to be a direct replacement. Problem is the vent doesn't use a piano style hinge like my old bracket. So that means I have to find a means to get this vent attached with a different hinge set up. Unfortunately it's the only replacement there is so I am stuck adapting instead of just getting an exact replacement

The cover fit great

As others have mentioned there's really no other choice. It fits although the material is thinner, the weatherstrip is applied so poorly it wouldn't seal without re-fitting it, the hinge is riveted in place about 1 mm lower than the original so it stresses the plastic cover when closed and will <just> barely slide into the flange. Also found that the new aluminum rail supplied is cut about 1 mm too long so if you try to fit it in place as-is it will crack the plastic cover. Make sure to test fit it first, you'll want to ease the top edges with a file or grinder so it will fit the rounded shape of the cover. Oh, and of course absolutely no installation instructions so make sure to find an appropriate video to learn how to remove/reinstall. Plus, as you can see in the photo, the packaging is ridiculously inappropriate--somehow mine managed to survive the process unscathed, I really don't know how. I'm hoping it lasts a year...Update, 15 months later--so far, so good, still fits and works just fine.

Fit was good , replacement on roof of an enclosed car hauler .
