Julie, one additional factor you should probably consider is how many people and how much cargo you will be taking with you. While a number of people do tow 13' eggs very happily with Elements and CRVs, their 1500 pound capacity is marginal. If you will be traveling with more than one or two people, or bringing a lot of extra stuff, I think you will be much happier in the larger vehicle.
We own both a CRV and a Pilot (previously a Sienna van), but with four people, bicycles, outdoor kitchen, extra icebox, awning
, plus mountain and canyon grades to deal with, we've never tried to tow with the CRV. If it were just my wife and I packing lightly, the CRV would probably be fine.
