tranns cooler

[2011 keystone]

Hi I am towing a 2011 hideout 26b with a 2002 chevy avalanche 5.3 with factory tow package. Do you think the stock trans cooler is big enough? Or should i upgrade to a larger after market cooler? Second ? is I have a eas-lift wd hitch should I add a fricton sway control? thanks for any advice!
