towing questions

first let me say i've learned sooooooo much from this site, thanks to everyone, now my question,-----i have a 2004 2027 TM, pulled by a ford explorer 2006, v-6 4.O----i've only towed a few times but i live in az and both the TM and the ford do well in steep mountains-----BUT when i bought my new ford i really wanted a stow and go chrysler----i was told sent it was front wheel drive it would never pull my camper in the mountains, but it seems like there are some folks out there that have front wheel drive vans--- could i hear about the engine size, weight, brand of van etc----i might have my facts confused but would really like "real" feedback---thank you, sharon
