For anyone that does any amount of camping, there are two catalogues you
need.  Camping World and E&B Marine.

For E&B Marine call 1-800-BOATING.  For Camping World, 1-800-626-5944.  E&B
is an excellent source for solar powered roof vents, (all one piece) and
special battery charging equipment,etc.  Camping World sell really nice
chairs, awnings, water tank chemicals etc.  Prices need to be checked but
the catalogues are great sources for ideas.
