i currently have a 2006 V8 and test drove a 2010 SR5 last week and it felt
HUGE to me as well. i totally understand why the proximity sensors and/or back-up camera is standard on the 5G. the bigger size/feel wasn't
entirely a negative/bad thing, but the analogy to an F250 is apt. it also seemed to handle a bit more "trucky" compared to my 4G. i didn't think the throttle response was all that impressive, but like 4Ryder, i didn't punch it with the salesman beside me
when i got back into my 4G it felt like a racecar, though. the V8's torque is hard to miss—it's there as soon as you step on the pedal. my 2¢.
