You can do it, but if you have never towed before, be aware of a couple of things.
If the Sedona has an automatic with overdrive, you should lock out the overdrive. An auto that has to hunt back and forth for the right gear all the time will cause the converter in the transmission to unlock and allow slippage, which creates heat, and heat kills trannys.
Going down a mountain grade, you must go as slowly as you went up the other side. Shift down to hold the rig back, using brakes sparingly for brief bursts. If you ride your brakes too much they'll overheat and give out, and you'll be a runaway rig.
If you decide you want to upgrade to trailer brakes, look under the trailer behind the wheel. If you see a square metal plate with probably 4 holes at the corners, that's a mounting plate for brakes; add the brake kit, wiring on tug and trailer, and you're set. If there's no backer plate for the brakes to mount, you'd need a new axle with the plates and brakes.
I once long ago towed a U-Haul 'egg' camper trailer with a 4 cyl Dodge Omni on a 2000 mile vacation from MI to CO and back. 90 HP didn't do so well, and I only drove 50 mph or less most of the time. But we had a nice vacation (other than some issues with the trailer's furnace and leaking front window). Not saying I'd do it that way again; now I'd want a few more horses (which you have double) and trailer brakes.
