base

I just bought a 2022 Jeep Grand Cherokee Trailhawk 4xe to flat tow behind a class A RV. I have not been able to find base plates that fit this make, model and year. Does anyone know of any base plates for this vehicle that are available in the market?

Has anyone installed MEGASQUIRT, im trying to find a good base map to start with for tune before I start. 1993 jeep cherokee 6 cylinder, rebuilt motor, better cam, with turbo. Any base tune ideas would be helpful. thank you
