Bill,
Stan offers a wide variety of options because of owners requests over the  
years. Try to envision what your use of the boat will be and what basic  
equipment you will need to accomplish it. There are all sorts of electronics  
available, but my experience is that the more crap you have on the boat, the  less 
time you actually spend sailing it. These things are nice when they work,  but a 
real pain when you are trying to fix them.
Ventilation is really important if you plan to overnight on the boat, even  
up north in the summer. I live on the lake where I sail, so I spend very few  
nights on the boat, opting for the comfort of an air conditioned house.
Porta potties are simple and seldom break. Marine heads have a lot of  
issues. Front opening ports do not leak if the seals are kept clean (wipe with a  
damp cloth). Stan has covers for them and they keep most of the rain water out.  
As Ed said, just wipe it dry with a rag.
The R22 is a great boat and I know you will enjoy yours. Welcome to the  
Rhodes community and don't hesitate to ask a lot of questions. Perhaps it would  
get us off political topics. Or not.
