Do I really need a 6.2L Super Duty?

I haven't exactly written the 6.2L off yet either. It's worth keeping in mind that the 6.2L is still very early in it's development. It's a brand new engine architecture, whereas the Ecoboost V6 is part of the Duratec V6 family, which dates back to the 90's.
I have no doubt the 6.2L has a lot of potential which Ford has chosen to leave untapped until they see what the competition is doing. I'm sure they're waiting to see what GM does with their HD trucks once their next gen gas engines are released.

Small Update!
Just completed another trip with the eb150 and 5ver, this one the longest at 700 miles round trip, Avg 10.2 going and 9.2 coming back. Driving was 95% interstate at 65-70 mph. Truck pulls well; it really shines accelerating and holding the higher 5th and 6th gears; however not much engine braking in this little V6 as you decelerate and the stability is not as good as the F350 6.2 naturally, its not bad it just pushed around a little as its at its max weight, basically i was more aware of 5ver as cross winds hit.
Have a bunch of data log equipment on truck some info during trip:
EGT = 1312 f max
ECT = 214 f max
Trans Temp = 201 f max
Boost Air Temps = 124 f max
Air Charge Temps = 82 f max
Engine Load = 177% max
boost = 16 psi max
timing - high engine loads at 2000 rpms = -1 to 0 advance from TDC
Steady state Boost at 65-70 about 5-6 psi
Knock sensor retard - didn't vary much -2 max seen
Truck specs are max payload, max tow package 3.73 gears

Excellent reporting info! It great to see the 3.5L Eco being worked...and getting real results.
Regarding the engine braking issue. I'm assuming you were in Tow haul mode. Which is good, but for more engine braking effect...did you try the SelectShift or manual mode? Wonder if using the tranny to help with slowing down would have made a big difference?
Would have been nice to see...if the tranny temps started to climb using SelectShift?
Still good to hear the F150 is up to the task with that large a load.
