Even 12 "configurations" (not counting color combinations) is still orders of magnitude simpler than, say, Ford.
I challenge you to find two, identical Ford trucks unless they were ordered at the same time for one customer's fleet use. Not only do you have multiple engine choices, but different cab configurations, bed lengths, drive wheels, axle ratio, option packages, individual options...the number of variations for the "same" truck is virtually endless. There are literally tens of thousands of possible combinations.
The total possible number of trim, drive, and color combinations from the factory for the 2017 Ridgeline is exactly 67 - each person who buys one will have one of 67 unique combinations of interior/exterior color, number of drive wheels, and trim level. Broken down by each model...

EDIT: Just looked at the Ford website. The F-150 has...
3 cabs - regular, supercab, supercrew
3 boxes - 5.5', 6.5', 8'
4 engines - V6, V8, and two turbo V6s
2 drive systems
8 different types and ratios of rear axles!!!
6 different trim levels XL, XLT, Lariat, King Ranch, Platinum, Limited
13+ different paint colors - even more combinations since some are available in two-tone
multiple interior colors
dozens of option packages and individual options
See why no two F-150s are ever identical? Of course, with so many of them on the road, there has to be a variety or they'd all look like a fleet of taxis, work trucks, or police cars.
