Hello all.
I am looking for a LP tank and skylight for my '84 Westy?
Anyone have these used? I need the whole skylight assembly. Mine is cracked and
water has gotten inside it and stinks something fierce! Does anyone recommend
something other than the original?
My LP tank had a small hole in it. So I need a replacement ideally with the fill
valve as well.
