I have a 2014 Explorer which I do like. Unfortunately it went back to the dealer for a variety of work while it was under warranty. If you go with the Explorer look the paint over carefully. We had troubles with the paint blistering, which I was told by the dealer was a problem with the 2014's. I also had a bad wheel bearing, a leaking strut and an idler pulley go bad. These last three I believe are more uncommon. I chose to replace the stock tires (Hankooks) due to poor traction in the rain. I highly recommend Michelin LTZs, their replacement. Though it's been a bit of a lemon I do like the Explorer and am not trying to scare anyone away. Obviously be sure to look any vehicle over carefully before you buy.
I haven't towed anything with our Explorer yet, so I am no help there. Keeping the weight under 4000 lbs is smart. I don't think I would want to go much beyond 20 ft in length - these are not long wheel base vehicles. Good luck to the OP on their decision.
