Most fuel efficient vehicle to tow an average-sized teardrop? One of the things that attracts me to a teardrop trailer as opposed to a van, say, is that I think it would be more fuel efficient (cheaper and more environmentally friendly). But what vehicle would maximize fuel-efficiency while still being able to tow a decent teardrop (\~1200 lbs?)? I'm thinking a RAV-4 hybrid but maybe an even smaller car like a Prius would be capable.
