I just got back from Busses by the Bridge, in Lake Havasu City, AZ.  Lots
of photos at: http://www.oldvolks.com/Events/BBB/2000Photo/

While there I got the name of a man who makes a hatch latch.  It is a steel
bar that holds your hatch open a few inches for ventilation while still
providing lockable security.  We have been using one for a couple of years.
 It's $10.  He only has a few left and isn't planning to make any more.

He also makes a slick aluminum pin that holds the front wheel lined up
while you put the bolts in.  $5 for that.

His name is Jim Harvey, and his email is harveyhouse@uswest.net

As usual, I have no connection with him, etc.
