I ended up getting my fiance the GoGirl pee tool. This was supposed to allow her to pee standing up. Well needless to say it didn't work. She ended up with a crazy pee foot situation because it didn't seal properly. She ended up becoming a total pro at trail relief technique, more specifically, the squat and twerk method.
I also bought the off road commode, AKA Hitch Sh*tter. By far the best purchase I've ever made. She used it a few times, but it was mostly used by me. I pinched a loaf on Imogene and black bear, so sorry if you may have encountered that. I tried to dig a hole or bury it the best i could, but shovels don't penetrate rock very well. Definitely a life saver though. Even used it a few times on the drive back to GA. The only thing that bothered me is positioning the truck so you don't get loaf or urine on the shorts, a lesson learned the hard way.
