Lease info for 2016 Dodge Durango Limited AWD in NJ

Hi all,
I’m looking to lease a 2016 Dodge Durango Limited AWD in NY/NJ metro area. I have a Honda Odyssey 2013 where lease ends this month (May). I think I have about 2k equity in the minivan. $19800 buy out at end of lease. according to KBB its worth about 22000 if trading in. Questions:

what are the MF and RF for 36 & 24 month with15k miles?
could I really use my ending leased car as down payment?

thanks for your help.

PS, I was originally in the market for Kia Sedona but wifey wanted to move away from the minivan world cuz she wants to look cool again… whatever
