monthly lease payments for 2017 Ram

Hi everyone, I am leasing my first truck and looked for months to find a good deal and contacted multiple dealers and overall I think I got a really good deal, but I have been reading all the forums here and its obvious you guys know a LOT more than I do about the financial side of this, and with my terrible buyers remorse I just wanted some confirmation if possible.

So I was wondering how good of a deal I really got/if I did. I am leasing a 2017 Ram Big Horn 4x4 slt crew cab with a 5'7" sprayed bed with a tonneau cover and I think pretty much every option including nav, and power converter, but no moon roof. I put $1500 down and am paying $440 per month on a 36 month lease with 15k per year. They also took care of my last 2 payments of my previous car lease.

So what do you guys think? Did I do ok or should I have found this forum before I leased???
Either way I appreciate the feed back. Thank you!
