Let's see what Yoda has to say on the subject of Montero capabilities overall, and in regards to towing:
"Size matters not. Look at me. Judge me by my size, do you? Hmm? Hmm. And well you should not. For my ally is the Force, and a powerful ally it is."
But my Jeep is from the same era as the XLS and it offers great torque and 65 more horses.
"You must unlearn what you have learned."
I think if we had the diesel engine option that you can get everywhere else in the world but the US, we'd pretty well have it made. Give the new Monty some "time in the saddle", I've really come to appreciate the overall capabilities, and I wouldn't trade any of the Montero's features for a little more torque and horsepower.
My guess is the Limited with the 5-speed "sportronic" vs the XLS 4-speed trans might be a little more friendly towards keeping the engine in the higher torque range needed to more happily pull the boat. The XLS has the better 4.9 final ratio, but I really like the steps between gears of the Limited 5-speed, and the ability to easily switch up/down when in the hills, using the side gate option on shifter.
While we're having a little too much fun, Yoda has one more piece of advice:
"Yes! Yes! To Obi Wan, (Michael Brown), you listen."
I'll say again, just a change of expectations, once you get to know the truck and work through the oil leak/maintenance gremlins, I predict the days in the Jeep will become a distant memory, (remember I'm a Chrysler and Jeep fan...). The solidness, and quietness of the body, the relative gracefulness over the washboard roads, reminds me of my mountain bike, able to carefully, slowly, safely pick my way through off-road hazards, where too much power and speed would fail me. The comfort and room of the Monty, voluminous rear cargo space, and it is so convertible. The tumble seat option yields lots of versatile space.
Welcome to the club, research and get the right springs, while you're at it, if your truck doesn't have an OEM receiver hitch, look for one. I found mine in the junkyard, along with the factory light wiring harness. While it's a fair amount of work, it's more stout than aftermarket, and the receiver sits higher, to reduce departure angle somewhat.
