Female Urinal Spill Proof 32 oz (1 Pack) - Urinal for Women - Pee Funnel - Women Bed Pan - Portable Urinals for Women - Sturdy Female Urination Device for Car Travel, Road Trip Essentials

Try the kind that collapses telescope style. I used this when I car camped in my little crossover and loved it. Sometimes I would set it outside the car to use at night; no one was around and it was dark, so I had no qualms about it. But if I needed to use it inside, the telescoping feature made it so I could just put it on a shallow setting and set it on the seat to use. For just peeing, get a portable urinal. I'm a woman, and I use one that's basically a little container with a special shaped funnel on the top. I can use it standing, or I can get on my knees to use it without getting out of bed. It was a lifesaver. This is the one I have, although I bought mine on a Chinese website for three dollars. I've never had a leak with it, and even my middle of the night power peeing isn't too much for it lol: https://www.amazon.com/Female-Urinal-Spill-Proof-Pack/dp/B0B5KYY1MH I also had a privacy cape and used it if I wanted to use the toilet outside during the day: https://www.amazon.com/Portable-Changing-Shelters-Lightproof-Dressing/dp/B09T35X8MZ
