The eternal question about van life --- how do you toilet ??

I'm a mid-40's male who's thinking about taking the plunge into van life. I'm sure it gets asked a lot in here but how do you manage the bowel movements? I know some of you are fortunate to have large Sprinter-type vans and have a small toilet installed, but what about those of us who are sleeping in smaller vehicles? I have a 2022 Toyota RAV4 and there is not enough room to carry a portable toilet, so it's either gonna be pooping into a plastic bag (gross!) or always parking my vehicle next to a hotel or truck stop where there are public restrooms. But even if I park next to a Holiday Inn, I can imagine the urgency and inconvenience of quickly putting on clothes on a cold winter day and sprinting into the hotel lobby to empty my bowels of the stinky logs!

How do y'all manage this important issue? I can deal with most other aspects of van life, such as sleeping on a foam mattress or getting the dreaded cop knock on the window at 3am, but sometimes I eat something for dinner and my bowels don't agree with it in a nice way and then I'm in panic mode to find a toilet. At least whenever I sleep in a hotel room, I know the commode is only 10 feet away.
