does the places you camp have bear problems?
if you want to camp in a campground that has bear problems, simply "turtle" your hybrid, if you are worried.
even at Fishing Bridge CG, in Yellowstone, where they ban soft-sided trailers, they will allow a hybrid if they "turtle", by not deploying the canvas ends.
Two miles down the road from Fishing Bridge is a campground that permits soft side campers (They post signs "No Bears Allowed"). Its a bit silly to use the bears rationale at Fishing Bridge to keep out soft side campers. I believe it has more to do with Fishing bridge being more amenable to motorhomes, etc. The campground is most always full so they do not need to try to attract other campers.
To my knowledge no one in a softside camper has ever been injured by a bear at Yellowstone, but as mentioned in the other posts you need to use common sense and not put yourself intentionally at risk - There is always a first time. I believe the bears are much more wary when there are many people around and thus they are more easily scared off.
My only encounter was with a black bear while camping in a tent. This bear had been at the campground before and was not leaving until he got all the goodies he wanted (I think he was related to Yogi). I practically had to push him with my car to get him to leave.
While visiting Glacier NP a ranger told me a good compressed air boat horn is as effective as bear spray (and much cheaper). Also some say wasp spray is just as good. However, bear encounters are rare and you are much more likely to be struck by lighting. Oh yeah, look up at those big limbs overhanging your camper and imagine what the wind could do.
Enjoy the great outdoors and don't become too paranoid.
