Gotta second this post.
If gas engines were a viable towing option don't you think the highly
advanced Current class of Class 8 trucks would use them? These are the
full-size over-the-road trucks that haul 40 tons at 75 MPH up all but the
steepest grades without slowing.
These diesel motors are are so powerfull now that the limiting factor on
speed or torque is what electronic limitations the owner has programmed in
for top speed and if the currently selected gear is strong enough to handle
the requested torque. Think about 1850 fp of torque @ 1400 from 13.4 liter
straight six with variable valve timing. And 6 - 7.5 MPH per gallon.

I haven't really followed this thread too much, but after the reply about
diesels, I thought I would toss in some more on that subject. There was
recently
an article in Popular Mechanics comparing full sized Chevy and Ford "one
ton" dualies with the big gas engines, 8.1 V-8 and 6.8 V-10. They wanted a
Dodge
V-10 but couldn't get one so they took along a GMC 2500 single rear wheel
crew cab with the Duramax and Allison trans that was available. All three
trucks were ballasted with 1000 lbs in the bed and hitched to identical
5th wheel trailers that weighed 10,000 each. They towed them 3000 miles,
coast to coast. The diesel not only got 50-80%
better mileage than the gas engined trucks under all conditions (about 18
unloaded) but out-accelerated them in EVERY category measured; 0-60,20-50,
30-70, and 1/4 mile e.t., loaded or unloaded. Not by a little either;
it flat blew their doors off! I was left wondering why anyone wanting a
large pickup would buy anything BUT a diesel. Some day I will...

Shawn,
Just one opinion here, but I would personally skip the whole suburban idea.
They are just large bricks with not enough horsepower to tow what you really
want without single digit mileage. I would recommend you locate a used
diesel (not gm unless its a duramax) and go this way. My Ford PSD is a 4x4
CC and weighs in at 7400 lbs. During the week we drive about 22 miles each
way to work 5-6 days a week at about 65-70 most days depending on traffic.
It gets between 16.8-19.2 depending on how I am driving. On the weekends, it
either has a 20ft bass boat behind it, which you can forget is back there,
and it gets the same mpg. If we are towing the car, then the car is 3400
lbs. with misc. gear and is sitting in a 28ft tri axle trailer. fully loaded
we are 17.5k lbs. rolling down the highway and we get between 12-14mpg.
Dodge Cummings will do the same but with a slightly lighter weight limit.
Nothing beats a turbo charged innercooled diesel for torque, power, and
mileage. Nothing. My trailer is a tag trailer and has all the aerodynamics
of a brick. Check around on ebay, carsoup.com and autotrader see what you
can find with under 75k miles on it. They are coming down in price and will
still have higher resale then that burban when you have 150k miles on em. I
just rolled over 12k and the motor is just starting to break in. I should
start seeing over 20mpg once I get fully broken in and keep it under 70 on
the highway. Just my two cents worth here. It takes about 70k miles to break
even on the price difference on a new truck, but its only about 30k miles on
a used one before you are in the same price range and operating cost. Run
the numbers for your self and check it.
Later,
Paul
