For a hot shower check out this link for an inexpensive propane alternative. http://www.zodi.com/T6170.html
Sometimes you can find these on ebay. Instant hot water!
We use the propane Magma
grill for most of our cooking, but have used a cheap butane portable
stove, and also an alchohol
stove. Both worked fine, but took longer to heat up than the
grill. When it''s raining you don''t want to be standing outside to
grill something!
Have fun!
