We just bought a 2016 Town and country van and with the stow N go seats the thing has 4' X 8' clear, flat space behind the front seats.
This could be used for air mattress etc.
I tow a heavy 16'
Scamp and the tow rating for this van is 3500 lbs with WDH and 1800 without.
A T&C with the towing package has self leveling suspension and heavy duty cooling for the engine and transmission.
It's hard to find one with the complete towing package, but for the past several years they have had the suspension and heavy duty stuff, but nit the hitch and wiring.
If you were to buy an new Pacifica the towing package is less than $1000.
I bought a T&C used from a dealer that was a Hertz rental on the GDP (Guaranteed Depreciation Plan) where they had a buy back price set for X number of months so that they can add vehicles doe heavy use seasons.
My van had 7800 miles on it when I bought it.
It had the suspension and heavy duty package and I added the OEM hitch and OEM wiring harness.
Just one thought to add to the others above.
The T&C has a 6 speed auto transmission and the Pacifica an 8 speed ZF auto.
The engine is a strong 3.6 V6 used in every V6 application in the line.
Previously we had a 1998 Voyager van for 230,000 miles and got good use from it.
I hope the T&C does as well.
