It is really splitting hairs. If a person can't put a 1/2 ton or Hell even some 3/4-1 Tons (like a RCLB or Extra Cab SB) in the same spots as a midsize they need to look at their driving abilities.
Saying these new midsizes are more nimble than a current fullsize is laughable. (that wasn't directed at you)
I currently don't need a fullsize truck, but when the time comes to buy a new truck...I don't see the point or any major advantages of buying a midsize. The economical advantage ship has long sailed away...
I still see the mid-sized trucks (Tacoma, Frontier, Colorado and future Ranger) as offering distinct advantages over "bigger" trucks when it comes to mobility, not to mention cost of ownership (purchase, fuel, maintenance). Yes, even the mid-sized trucks are bigger than their predecessors, but they still offer a smaller footprint than what you get with a double-cab F-150, Tundra and certainly a 3/4 ton. Now full-size trucks seem less distinct from 3/4 and 1 ton's IMHO. Pricing and engine options aside, the 1/2 ton seems to have morphed into a pickup that has nearly the same footprint of a 3/4 ton, but only a fraction of the capability. And I suppose that makes sense given that they seem to be the truck of choice for guys who want to own a truck but have no real need for one.
Also, people who complain about the pricing of these high-end mid-sized trucks need to put things into perspective. What is the going price for a new Raptor? $57k-$64k isn't it? And that thing, while fast and capable, is wider than most 3/4 ton's and has payload that is worse than most mid-size trucks and has about the same towing capabilities. But people will still line up to spend mega $ on those things.
The ZR2 and AEV variant might cost a lot, but they are no different from the other offroad-oriented models coming from other companies.
