Macka, if you've got HOG membership, check out the H-D Dealer rental deals through HOG, they work out much cheaper most times.
I've rented Road King from Eagle Rider out of San Franciso, Heritage SoftailClassic from Eagle Rider in Denver, and an Electra Glide from the HOG dealer deal in Italy, in that order,
If I go again it will be on an Electra Glide for a long trip, or a Street Glide for a not so long trip.
Edit; Mate, the FLHTCU impressed me that much on the last trip that I placed an order for one when I got home.
