Bill,
in reply to your question, a couple who I rode with on our way to the Americade rally,....anyway they rode their HD full dress w/ sidecar from Florida to our meeting place in Mass., we then proceeded on a route to VT., then on to NY....when we hit Manchester VT, their drive belt grenaded. I was behind them...rain was pouring so hard it looked white!
They called their HD roadside assistance plan,....fortunately we had a voyager mini-van as a chase vehicle and it served them good refuge for comfort & warmth. They told me a wrecker was dispatched and for me to continue on.
I met up with those folks the next day, they said that it was only a 45 minute wait for a tow vehicle to show up, ...said the driver took them to a lunch place for a bite, then to Fort Anne HD in the area. The dealer had done the repair on a Sunday! They were very pleased it worked out for them so easy...of course we were fortunate to be quite close to neighboring towns, and had good cell signals for the occasion.
I say score one for the HD roadside plan.
