I've been towing a 1977 pop-up trailer that sleeps 8 with my 2001 Grand Caravan for a couple of years now with no problems. I've installed both the tranny and engine coolers beforehand and am also going to install load-leveling shocks soon. If you are only towing this car a short distance then I wouldn't bother doing any upgrades unless you are going to be doing any future towing.
