My idea or roadside assistance is two stage, the first being self assistance with a good tool kit and good knowledge of what is fixable on the road and what is not; and 2) outside help with either AMA or AAA. It is extremely annoying to call up a tow and find out later you could have easily fixed the problem yourself and been up and out of there in short order.
Many of the Rocket's issues that can strand you on the side of the road can be fixed, or temporarily fixed, right there. These include failing "safety" switches, ignition switch, starter relay (have an extra on hand), dead battery (I keep a portable jump battery in my saddlebag), fuses, flat tire (portable pump and tire repair kit), etc. We should all be able to tell quickly whether we are SOL or have a chance to fix it on the road. SOL would be things like blown output shaft bearing, cam chain, stripped splines etc.
The absolute last resort should be getting towed. Even in the best scenario that is going to take a lot of time and if you are a long way from home, a night or three in a motel. Harely riders nearly always have help right around the corner, that is one good reason to ride a Harley.
I have AMA Motow, but 35 miles is not good enough. AAA may be a better option. I found this on the net:
AAA Plus RV includes all Basic and AAA Plus services as well as the following services:
100 miles of towing For eligible recreational vehicles, which include motorhomes, travel and boat trailers, cars, vans, pickups with campers, and motorcycles.

We've had this policy for the past several years and have had our motorcycle towed many times. Our last ride last season ended in an 80 mile tow -- where we were given the choice of which town in a 100 mile radius we wanted to be towed too.
Good luck!
