Thanks for the input - decision made (I think)
Finnally made it back here. betwwen work and getting lost in other posts, never made it back here. Amazing at the amount of knowledge and experience on here. Thanks for all the input. Much to think about and consider. One thing I failed to mention in the original post, I have multiple artificial joints. A shoulder, knee and both hips - sort of a modern day iron man with all the surgical steel in my joints ;) So, being able to mount/dismount and sit comfortably was a big decision factor. Since the seat sits slightly lower, my assumption was that the F3 was going to be the better choice. After much going back and forth between the two, surprisingly the RT was actually easier for me to get on and off of, as well as the seating position. With all that and the test drives, I have put a deposit on the '18 RT to hopefully complete the paper work and pick up later this week. Again, thanks to everyone for the input and all the things to think about. Now I need to quit thinking and second guessing my decision, get it picked up and start riding it!
