Hey there @rarsauce!
Thanks for reaching out to the Community!
As a curvy woman myself, I can understand some of the challenges with finding the right fit. As a result I mostly steer away from a structured pant and have leaned into leggings pretty heavily. No regrets here!
Right now my absolute favorite leggings are the REI Take Your Time Leggings. What I love most about them is how soft and breathable they are, high-waisted, and they have deep pockets! A close second would be the REI Active Pursuits Capri.
Hope this helps and enjoy your road trip!
