In my opinion, according to what you are looking for in a ride, The RTL is the way to go.
The list price is 4K more than the base model, but that can change at the point of sale. I got my RTL for $1500 less than the sticker price and got the driver backrest thrown in the deal.
The RTL has a detachable Top Box (trunk) that has a comfortable passenger backrest built into it, 2 more speakers that give you a surround sound in the cockpit, storage space that will hold an additional 16 gallons of gear giving you an additional 33% of storage. A must have for long distance touring. Besides, your wife may change her mind about riding when you bring this baby home. Mine did. I also purchased the back cover to replace the top box (around $230) in case I want a sportier look, but honestly, after my she who must be obeyed (wife) road on it with that set-up, she hated it after being spoiled with the OEM top box. :lecturef_smilie: Both driver and passenger seats are heated as well as the passenger hand grips. If you are touring, you never know when the climate may change, especially in higher elevations. Not sure if it makes a difference, but the RTL is 2" longer than the standard model because of the trunk.
The RTL also has LED front signature lights which gives it a little attitude on the front end.
In addition you get self leveling rear suspension that adjusts accordingly to weight added.
The front trunk (frunk) has a soft liner and has a light in it so you can see into it's vast depths.

To me, the RTL is the only way to go if touring, whether one or two-up.
Both models are available in either chrome or dark editions. I'm a chrome guy, so I forked up the additional $1000, but many like the dark sinister look better.
Whichever you purchase you're gonna have miles of smiles on it. Good Luck with your purchase.:2thumbs:
