It is too bad you had to completely (almost) redo your bike. Any dealer that would not take a bike back after one day would be on my chit list to the point where they would be begging me for the bike back after I was through exposing them on every social media outlet available. Additionally, isn't there a 3 business day right of rescission there on any contract you sign? That's pretty much in every state.
Anyway, your bike looks great! Love the paint scheme! I have a 2013 FLHRSE5 and it came with an incredible 200W sound system, front and rear speakers, as well as lower (fairing - not sure what is called?) in the front. I have no idea why they decided to eliminate those features.
My biggest issue has been the extreme heat that comes from the header pipe from the front cylinder. I have Jackpot header pipes with no cat and it is still unbearable when it's hot out. My right calf, right under my knee, feels like it is in boiling water. Granted, it's been close to 100 deg and humid, which is not optimal for any bike, but my 07 Heritage never came close to this excruciating pain. Called the dealer and talked to both service and parts - they both said that is the way it is with that engine and know of no solution. I don't know what the hell I'm going to do in Sturgis this summer when I'm downtown, it's hot AF and I have nowhere to be able to get off and cool down cuz there is a huge line of bikes.
I hope you enjoy your toy and it brings you many miles of happiness!
