Thank you all for the replies!
Pretty amazing thing about Kia. The same engine and transmission in the Hundai version of our sorento is rated at 2000 lbs. lol. Funny thing is all 4 Cyl Sorentos are rated at 1650 lbs regardless of options etc.
I did call The Dealer today and they gave me the response you all suggested they would. They told me I don't need one because there is one built in. I know there is one in the radiator but that's all. I see no external Aux Tranny cooler.
And yes, I think I am being reasonable. I do t expect this Sorento to pull an Airstream over the Rockies. Lol.
But a 1200-2000 lb PUP in Tennessee? You betcha!
The motor didn't strain or struggle at all it just performed like normal.
I put the transmission in manual mode and mostly left it in 4th gear. It's a 6 speed transmission.
I have learned that I don't like flat 4 pole connectors. My RV 7 way plug was sooo much nicer to use.
Thanks!
