Without trying to influence the decision pro/con,
here are a couple financial realities:
Cost of gear change out the door: @2000$- increased torque and
power will come with 373s, but so will decreased mileage upon
the altar of higher RPMs. Don't forget you'd have to own the
truck for @ 4 or 5 years after the modification to reasonably
justify the expense.
Furthermore, the engine's PCM would have to be re-flashed so
your ABS doesn't go bonkers, and your speedometer reads the
correct speed with the new gears.
A CAI will give you RPMs from your 4.8L faster, and only costs 250$.
You can install it yourself in a couple hours. IMO, a 4.8L is a fine
engine, my GF has one in her pickup. Unfortunately, 323s, while
great on MPG for highway driving (wish I had them)
give you abysmally poor torque.You're trying to make an
Interstate "sipper", made for the long drives at low RPMs
on the highway, do short-run, hi-torque,boat-hauling duty.
Depending on how much you haul the boat, perhaps
a change to a different vehicle may be in order.

mods?
Why do all these mods? the price of which will not add to the resale.
Find the price of the correct one (4x4, 5.3L) and sell yours. the difference may be a bit more, but it's the correct thing to do.

to enhance it, modifications generally have a negative effect on "book" value.
So making these changes calls for a commitment on the owners part,
as keeping the vehicle for 5+ years after they are made is important.
It worked for me, and my 2004, but I'm, fortunately, just not average...
As previously stated, a change to a more mechanically suited vehicle for
boat hauling might be in order.

If the OP just bought the vehicle and has a loan, then trading it in now just for the larger engine would be Ridiculous. Why get into an upside down loan to tow a boat ocassionally.
