Yeah there is no such thing as a V11 and the V-10 hasn't changed in years. I have the exact same V-10 in my Axis as that (Axis/Vegas? 27.7).
Before signing on the dotted line go download and read Ed's excellent crowd sourced Axis/Vegas owner's manual found here:

(If you haven't already)
There really isn't much difference between the 2018 and 2019 Axis/Vegas units (you mentioned just about all of them--2019 probably has a solar controller that the 2018 doesn't.) Even the Ford chassis there isn't any difference--not sure about any center console as Axis/Vegas RUV's don't have a center console (center console = armrest+storage between driver and passenger seats)!
