It will be fine. Get a high quality weight distribution hitch with sway control and have it set up by a hitch shop who knows what they are doing, a brake controller and learn how to adjust it, and good towing mirror extensions.
When the rig is set up and loaded with passengers and gear (amount of each in the Explorer will limit the other), take it to a CAT truck scale where you can weigh each individual axle loads and compare that to axle limits for truck and trailer (GAWR) posted on stickers on the SUV's door sill and trailer tag. Those weights will tell you if you are overloaded, and help you optimize the weight distribution hitch settings.
The Explorer is a stable vehicle with it's full independent suspension if you don't overload the rear with gear and trailer hitch weight. It's performance will be take you where you want to go, if it is acceptable to slow for climbing and descending steep grades (most of us do that for safety and to stay within the capability of our truck). Learn to shift down your transmission for these tasks for best performance and safety.
Successful towing is about hitch and vehicle setup, and driving on the safe side of your equipment, traffic, and road and weather conditions.
