I'm new to this forum; I hope I can tap your experience. We need to purchase a bike rack and are leaning towards a trunk-mounted model because it could be more easily swapped between our cars (a Jetta and a Subaru Legacy wagon). Plus, we're contemplating a minivan in the near future, so a roof rack could become more of a hassle with a taller auto. At a retail store (LL Beans) this morning, we were told that one should never mount a rack on the glass of a rear hatch (i.e., our Subaru) because it places too much stress on the glass. I'd never heard that before, I routinely see people doing precisely that, and I've never heard of any problems. But what do you think? Should I heed this warning? Have you ever heard that this is a concern?
Many thanks for your thoughts.
