One good example of the difference that I saw was the V-series 3105 had a bedroom air but it was not ducted. The 3200 had a ducted bedroom air conditioner and it had double the outlets of the 3015 - 2 in bedroom, 4 in kitchen/living area, and 2 in the garage.
The 3200 also has the recessed puck-style lighting while the V-series has the ugly camper lighting.
