It's good to have a look around to see the differences in various models so you can get a good idea of what you are looking for, but I've found that doing a factory order gets you exactly what you want. I was also fortunate to be able to attend a Ford "road show" where various Ford trucks were able to be driven with competitors units available for driving for a comparison.
Perhaps after the launch of the new F-150s occur Ford will be back to offering better incentives, I understand that they backed off to ensure that stock would remain at the dealers during the extended plant change over period. I found I got good pricing during the summer "employee pricing" events here in Canada, the incentives brought the pricing even lower.
