When you say "car camping," do you mean setting up a campsite outside of your car, or actually sleeping in your car?
(Please excuse my ignorance!
)
For me it's all of the above and more. The car or SUV has all your 'stuff' to
put to use in relation to the place you find to camp. There are plenty of
shower possibilites in my 'kit', as well, to be clean-as-a-whistle
while traveling.
