It is a natural reaction of most motorcyclists to try to make it home...limping or not. I sure wouldn't blame you for trying, especially when the other dealer wouldn't/couldn't help and BRP said they would meet you at your home dealer. Sometimes you roll the dice and they turn up snake-eyes.
You would need the BEST warranty, either purchased or under a promotion, to get road service. As you have discovered, there are severe limits. One thing touring riders have come to rely on is their credit cards, I'm afraid. I also stash a hundred or two in cash on the bike, in case of wallet theft or a cash-only situation.
If your problem turns out to be the same as Bluestratos. it worries me. Repeated problems can spell trouble. I hope these are isolated cases. BRP need for the 2014 RT to be bulletproof in the light of last year's difficulties.
One of the hurdles Spyder dealers have to learn to leap is the stretch from recreational vehicle to touring road bike. Most Harley, BMW, and Japanese touring bike dealers will move heaven and earth to get a stranded traveler back on the road. That is part of what drives their touring machine sales. I spoke with Carlo and some other BRP reps about this several years ago, and they have made some gains in that area, but it needs to be stressed more, supported by BRP, and encouraged in their dealers.
