Another Expy question

I learned a great deal about my big families payload issues last year from this forum, and we never bought a TV. (3 teens, 3 adults) We have decided that an Expy fits our needs the best as an everyday vehicle, and we may need to resign ourselves to the fact that it will tow a trailer with only the driver, and the family following in another vehicle. We typically camp within a few hours of our home so it's not a big deal.

There is an outstanding deal on a '14 Expy EL. Brand new only 39k. 4x4 with a heavy duty towing package. Says it includes this: Heavy-Duty Trailer-Tow Package (Heavy-Duty Auxiliary Transmission Oil Cooler, Heavy-Duty Radiator, Integrated Trailer Brake Controller).

1)Is that including everything what we need to tow?
2)It's such a great deal, but is it worth it to wait for the ecoboost engine in the '15? I see those as being at least 10k over this price. But is it worth it?

We do not own a TT yet. Will likely be on the smaller side, kids don't mind sleeping in tents. Mostly want the bathroom, running water, bed for me. :)

Would you snatch this up and use it as a TV?

Thanks!
