I have been using one of these on my non-westy Weekender for 3 seasons now,
and it's really nice, well made, and very convenient to use. Very compact,
light weight. It gets my enthusiastic thumbs up. Yes it improves ventilation,
but for real air flow, you need a side door screen - (mine is home made, and
I think superior to the one that BD sells) or at least door window screens
(see archives).
