Color me equal parts jealous and inspired. I think your paint is in really good shape as she sits but I can also appreciate an Expedition being worth a respray.
I have a soft spot for these machines since it was an '83 Expedition that got me into road riding in the mid-2000s after years of BMX and mountain biking. Rode the heck out of it built up like a racer until I succumbed to carbon fiber and later back to C&V. Oddly, I never configured the Expedition as a tourer. I agree it's remarkably fast and incredibly comfortable. Unfortunately, years of Houston perspiration took it's toll and it's now a rusty husk sitting in a box.
After reading your experience, it makes me want to relive some miles on the Expedition. Over the years, I've compiled all the original components and wheels so now it comes down to rust mitigation and repaint. I look forward to seeing what direction you decide to go.
