I guffawed at the 12 day shower record!
I'm on year 15, or is it 16? of full-timing, from being a totally newbie. I too downsized from a 27' Class C to a 24' Class B, and was happy I did. It's usually just me in my rig, and I work on the road, filming documentaries of family homelessness.
I can relate to all your learning experiences. Every. Drop. Of. Water.
I ended up writing a memoir/social narrative about my experiences and the people I met. For those interested, https://bit.ly/2ITtkZz
Thanks for your post! It's validating!
