With winter coming I decided this may come in handy and they're on clearance.

Portable Potty

We had a different make in our truck, but after wife's rectal cancer, it was an essential, not just a comfort or handy. She had greatly reduced control.

I'd miss having walls to brace myself with, while pinching a growler.
I'd also want to take that outside, because I might crap bigger than that thing.

That's why I prefer Trucker sized fitted briefs. They can hold up to 3 Cleveland Steamers.
I first tried one out, at the Mardi Gras in New Orleans.

I can't use this if I'm teaming. Strike 2 against teaming...

maybe your new partner will have his own.
Some of the earlier versions, were a 5 gal. bucket, basically... so if he's carrying stuff in a bucket, when you see him...
you'll know what all that growling is about behind the curtain....

TMI..... foul on the over sharing WW

LOL that is too funny! Hey I used to carry a pot of sorts. Nothing is going to be pleasant in a truck, but if you are stuck in traffic and have to go... well it is good to have anything!
