When I bought my Spyder in 2021 I was brand new to 3 wheelers, having just decided that after 40 years on 2 wheels a change was needed. At the dealership I sat down on an F3, and then on an RT and based upon that momentary impression, decided to go with the RT. I have been more than happy with my RT, and do not regret not going for the RTL since I have not missed having a top box, and never liked the feel of heated seats so I was glad I saved $4K with the basic RT (and an added passenger backrest). But other than the slightly different seating position, I really don't know what differentiates the F3 from the RT. Especially looking at the F3 Limited, it seems almost idential to the RTL. I'm curious as to what motivated others to go the f3 direction.
