I'm one of those "way-too-happy" 09 Road Glide owners. I had the choice of an 08 or an 09 when I bought my bike. It was my first Harley so I decided to spend the extra money to get all the "improvements." Here is my list of further improvements.
1. Keep making the road glide.
2. Offer the option of having the bike come with a tour pak at a reasonable price.
3. A oil temperature gauge instead of the air temperature gauge.
4. Better cruise control buttons. The cruise control buttons on a Goldwing are much easier to use.
5. Hinge the gas cap so that it opens toward the front of the bike instead of the usual arrangement of opening toward the back of the bike.
6. Make one or both of the glove boxes lockable and larger.
7. More power plugs.
8. Make a water-cooled version of the Road Glide. I know this is heresy, but I've never had to worry about getting caught in stop-and-go traffic jam on a hot day with my water-cooled bikes.
