Yeah, and with the way the full size pickups have gotten larger and larger,
Actually, if you look at pickups from like 1999-2014, a 15 year span, I think you'll find that most pickup trucks have grown very little in size, at least with wheelbase, OAL (overall length), and width. Well, at least with GM and Dodge. To illustrate, below are the measurements of a regular cab, short box truck from each U.S. manufacturer, one from 1999 and one from the current model year, 2014. You can extrapolate the other variations from these, I'd think. (Widths are measured without mirrors.)
1999 GM Silverado
Wheelbase: 119"
OAL: 203"
Width (w/o mirrors): 78.5"
2014 Silverado
Wheelbase: 119"
OAL: 205.6"
Width: 80"
So, the Silverado grew 2.6" in length and 1.5" in width in 15 years, not a huge increase.
1999 Dodge Ram
Wheelbase: 118.7"
OAL: 204.1"
Width: 79.4"
2014 Dodge Ram
Wheelbase: 120"
OAL: 209"
Width: 79.4"
Again, not a huge increase in any dimension over the last 15 years, 1.3" increase in wheelbase and 4.9" in length. Worse than GM, but not as bad as another brand........
Now, for the truck that's "grown up": the Ford F-150 (or should that be "blown up"?)
1999 F-150
Wheelbase: 119.9"
OAL: 202.2"
Width: 78.4"
2014 F-150
Wheelbase: 125.8"
OAL: 213.1"
Width: 79.2" (SVT Raptor is even wider at 86.3"!)
Good golly, Miss Molly! Ford has added almost 6" in wheelbase and 11" in length during the last 15 years while GM and Dodge have almost remained stagnant. So, I think a lot of the "larger and larger" is mostly illusory by creating more slab sided, hulking front ended trucks. Ford has done just what you've said, bigger and bigger. So, blame Ford.
And have you looked at an SVT Raptor in person? Damned thing is HUGE! Looks almost like a cartoon truck. Just over the top in so many ways. Needless.
