new and looking for skylight/vent help

[thebarber]

hey folks,

helping a neighbour who owns a 2018 hymer aktiv 2.0. she had the acrylic cover for her skylight (vent?) come off on the highway last year. trying to figure out where in north america to get replacement parts.

from searching the interwebs, i think the skylight is a remos remitop likely in the 600x900 sizing (she measured at 23.5"x31.5" - - but of course im not entirely sure where she measured from - - so i can only guess at the rough opening through the roof)

ANY help that members could lend would be appreciated!

OR, if anyone has some good ideas for fabricating some kind of cover, i/we/she is open to it!
