There is no fridge in my camper and the kitchen area is sealed up with units so the vents serve no purpose. Should I get a patch welded in or how would you approach it?

The vents that were on there just seem to be cheap plastic kitchen vents and caused the rust problem in the first place so I’m reluctant to simply replace with new ones. Is there a good vent I could use to avoid the welding distortion etc?

Does anyone know who made this camper type? I have no idea who made the high top etc and it might help me to source parts etc if I knew who built the camper.

Thanks guys!
