Re: 90 Leisure Van - water leak
We call them skylights. Sounds more "posh".
I would go with whatever works the best, is easiest, and costs the least, in that order.
One thing that gets mentioned often, is to try to prevent moisture from permeating the
outer shell, and getting into the walls of the van (rust/mould?). If replacing the window seals
would accomplish that, I'd go with replace over caulk, unless the damage is already done.
If there's any doubt, consult an RV specialist, maybe start with the manufacturer, and
see what they would recommend. Or google your question, and see if anyone else has dealt
with this, on another forum.
It's not a sprint(er) (unless you make it one), it's (hopefully) a marathon.
