Rans are good touring bikes I think. I have a way more recumbant bike and found it hard to use, though it was designed to carry racks. It's for sale when I get around to it.
I camped with some guys who where on Rans and similar bikes and they had come from penn all the way up the coast to northern New Brunswick. The had Bob trailers.
LHTs are a great bike too, but I feel that while they are good, part of the appeal is they just let people loose to create a bike from scratch. People seem to really get into that. I have seen some very expensive all the bells and whistles builds (as well as the reverse). At some point when spending as much as many do, one has to ask at what point does a custom frame become a logical upgrade. I see guys with all the billet parts electronics, fenders that would get them half way to the custom bike, and yet they are stuck on standard dimensions and features. So as long as the LHT is the perfect fit, or you are trying to sus that out, go for it. I mean, a lot of recumbents are really pricey, you could go full co-motion americano for what they cost, might solve your neck pain to be on a custom. I did the LHT type thing last fall, now I am building a custom bike. By the time I buy the tubes etc... and buy parts at retail, I could probably get an upper level custom with billet parts just because they source the stuff cheaper.
