I have a 2018 Kia Soul, and before I bought it I researched vigorously the issue. Kia did issue a TSB that it is ok to tow 4 down with the manual trans in neutral, and the key set to acc. The manual says nothing about it(as is usually the case) Be aware the 2020's are different in a couple of good ways. The base model with the stick shift is the one you want, and they are now putting the 2.0 liter in the base model instead of the 1.6 liter I have. That will be a nice improvement since the only complaint I have is not enough power when you get 3 people in it. The other difference is they have gone back to port injection instead of GDI(gas direct injection). There are problems with GDI in many different makes of cars, too much to explain here, but if you would like to know more go to youtube and search GDI problems. Don't buy a car with GDI unless it's a Toyota that uses two injectors per cylinder. With my Soul I use a Roadmaster base plate with a Demco Dominator tow bar, and an independent lighting system. The Roadmaster base plate is good, but if you can get a Blue Ox that's good also and a bit less weight I believe. Go to e-trailer and see what they advise for a 2020 Soul. You never know there may have been a slight frame change.
