You can tour on either a 2-wheeled recumbent or a trike. If it is a 2-wheeler, I recommend a long wheel base. It soaks up road shocks better and is easier to start (especially with the weight of a touring rig. I have successfully toured with my Ti-Rush. My Catrike Expedition would, I believe, be great for touring, although I have not yet done so with it. It is slower than the Ti-Rush, but when you are touring comfort is more important than speed.
