Hi. I have a 2015 mkc 2.0. I recently bought a 2020 tracker classic xl which the manufacturer states that the package weight is around 1800 pounds. I looking for some insight. I decided to have U-Haul install their after market tow package. My concern is the oem one that Lincoln offers has something additional like tranny cooling and sway control. Do you know anything about this? Also, the ball height seems to low so I will have to use a riser probably like 4 inches. Would you have any concerns towing a boat of this weight with the aftermarket tow package from uhaul?
