I can store 4 of the Camco hoses in my bumper. The elbows and caps I keep in a bucket. I spray lysol on everything AFTER I've washed it all out pretty good, also change my clothes afterward each time.
I keep two boxes of latex gloves in the storage bay and change out the glove every time I think I got something nasty on them... even a drop of water. The gloves are cheap ($8/ box/ 100 gloves in the box). I've used 5 pair in a cleaning session once, just because things weren't going my way that day. Still I wasn't willing to get anything on me or anything else so I kept swapping out to new gloves. Beats getting some illness because I didn't keep clean.
What annoys me is the guy who thinks it's ok to leave his discarded latex gloves there next to the sewer hookups. I have noticed this at a few CGs. Some folks just can't be bothered with cleaning up after themselves, I guess. Pass their mess on to the next guy. Nice folks, eh?
No longer full timing, but still camping 10 days at a time every other month.
