Denise's advice about crazyguyonabike is spot on. There are almost as many journals on their by recumbent riders doing trans-Ams and similar rides. You might have to sift through some good (and not-so-good) stories, but for you it will be an unsurpassed resource on recumbents, trailers, camping gear and locations,riding styles, abilities, route planning, challenges, achievements, and everything in between.
