You don't say what year you are looking for but the specification for my 2020 2.0l Sportage is posted below. The two right hand columns are the 2.0l, Ive marked them Manual & Auto. We have towed a two berth Elddis which had a maximum weight of 1350kg and the combination was a delight. We are currently waiting for a new caravan (delivery a month overdue ) but it is bigger with a maximum weight of 1550kg and I think it will be fine.
Note: image is from 2020 specification sheet.

Finally got around to sorting the image, it now shows the weights and each diesel engine for the 2020 cars, although Kia dropped the 2.0l engine not long after we bought ours. Pity, it's a good tow car. Personally I would avoid exceeding the manufacturers towing limit, prefering to keeping well inside it, but that is just me, others will differ. I do hope the original poster is alive and well.
