I have a 2008 F-150 with the 5.4 motor. Shortly after purchasing the truck, I decided to buy an enclosed 4 place trailer. The truck pulls the trailer great, from a stabililty perspective, but I am just not satisfied with the power. I can't justify dumping the truck this year as it is less than 1 year old. However, I am in the market to replace our SUV. I am thinking of an Armada, Sequoia, or perhaps need to go with a Suburban with the 6 liter motor. (I know the 5.3 will not satisfy me.) Bottom line is that I am wondering if any of you out there can provide me with some real world towing experiences with the Armada or Seqouia as they both has significantly more torque than my 5.4 Ford. I am concerned with the stability factor on the independent suspensions on the nissan and toyota. Additionally, anyone out there towing 5,000 lbs or more with the Chev 6.0, and what are your thoughts on this? Is the 1/2 ton Suburban with the 6.0 going to make me happier, or is the 3/4 ton with the same motor a better choice. If so, why. Sorry this is so long and Thanks in advance for the input.
