@jerrybanfield. I made a copy of the Airtable in Jerry's example for everyone! Here is the link: https://airtable.com/invite/l?inviteId=invgbaAaidhSvcPIo&inviteToken=3e85fd4207ff7659080036e5b59dac3c
Also: Here is my Airtable affiliate link that you can use if you are new to Airtable: https://airtable.com/invite/r/rnwPlJ6I
I used Jerry's affiliate link which is again: https://airtable.com/invite/r/qGLfO5Yn
Again, a Big Thanks to @Jerrybanfield who definitely deserves his due credit for the contribution!

EDIT*: I added columns to account for Power Down Payments!
