I hope someone may be able to help me out with this question. I have
a Sport Nautique and I am thinking of buying a new vehicle to pull
it. Right now I have a GMC Serria (5.3L V8) and I'm looking at trying
to save some money by buying more of a mid-size SUV (Highlander 3.5L
V6) to save on gas because we have to travel a bit of distance just to
get to the boat. The new Highlanders have a standard capacity of 2000
lbs and a maximum of 5000 lbs. The boat with full fuel, gear, and
trailer are 4000 lbs. What are peoples options for the Highlander to
pull it?

You will have to save a *lot* of gas to cover the transaction costs of
trading vehicles. If economy is the only reason, I'd forget about it.
