Well, unfortunately the list is getting smaller all the time.
Here's a great reference for you....Motorhome Magazine's annual Dinghy Towing guides:

The information in these guides is straight from the Manufacturers.
Jeep is probably one of the most used TOADS...but in recent years you have to be careful with many of their models. I tow a 2000 Jeep Cherokee Sport 4x4. Just put the transfer case in Neutral, the gear shift in Park, unlock the steering wheel. I also have towed a Dodge Dakota 4x4. Can't remember the year...early 2000 something.
Same procedure as my Jeep to prep for towing. I had that pickup rigged up with a pulley and ramp system that I could pull a 14' flatbottom boat on a trailer up into the bed with the tongue of the trailer up over the roof. I also had a Dodge car with a stick that I had set up. Just put in neutral, unlock the steering and go.
I think what you want to tow is dependent on what you want to do with it. That's why the Dinghy towing guides are so useful. You can look through the years and see what you think you'd like and would work best for you and go shopping.
As far as braking systems...wow...everyone will have their favorite. I bought a Brakebuddy back in 1999 or 2000. Still use it. My current coach had one in the storage bay when I bought it, so now I have two! Easy to transfer vehicle to vehicle. It only takes a couple of minutes to set up. I don't think it's the "best" but I think it's certainly adequate unless you're towing a very heavy vehicle, and perhaps then I might want something a bit more sophisticated.
