Your right the Heritage does have bags etc. but the one thing is comfort for two up! Not to say the Heritage will not be comfortable for you two but the space you get from a touring is a big plus! The touring models are just as fun as the Sportster, softail , lowrider! The thing is with a touring you can take the trips and feel very comfortable. The frames on the softails are different than the touring check specs and don't forget size does matter! Test ride the touring with a backrest for your wife and it will be all over my wife loves the comfort!
Post pictures after you buy it!
Good Luck...
