Honestly it depends . Depends on your riding ability and your size, if you can handle a bike and your a big bloke GO THE TOURER , The rt3 handles so well and she will find it EXTREMLY comfortable .
The tourque on the bike and its ability to pull away with a passenger , without dropping and running through the gears is why my wife loves it m because its so smooth . In fact you don't have to be a big bloke i just put Ikon shocks on mine and dropped it through the triple tree and its now lower than the t bird. handles better 2up since i done that has well
The T bird is great has well I love it my missis finds it very uncomfortable , and with the forwrd controls and t bars i love it for round town but if its over 100 mile its uncomfortable, so unless i go out and buy the footboards , windscreen ect , the T bird is more of a round town , boulavard cruiser for me .
So if you want the T bird for long journeys your gonna have to buy a seat possibbly footboards , windscreen and bags , unless you get the SE model which they refuse to sell us in Aust , for the same money or less you could buy the RT3
