View Full Version : Pulling 17,000lbs in the rockies

Thats close to the combined weight of my uncles new 3/4 GMC Yukon and 28 ft enclosed trailer.

The GMC has the 6.0L gasser and he just told me driving through the rockies he had to get behind the semi's a bunch of times and went as slow as 40mph pulling the steep hills.

Is this just a lot of weight for a small block? They don't make a diesel for suburbans or Yukon's yet. He cant do a pickup because of trips where he takes 7 people, you can't do that comfortably with that many occupants for thousands of miles.

The next best thing is the Ford Excursion but that has a terrible ride compared to his new Yukon's.

well its either suffer the terrable ride of the excursion, or continue towing at40mph, if it were me, id get the excursion and never look back.

Have you actually riden in an Excursion??? We have a 2003 Excursion with the 6.0 PSD. It rides very well, has plenty of tow power. We use it to tow our 35' Travel Trailer. Does a great job and rides good.

Isn't the 8.1L available? He's at capacity, you can't expect it to chug right along up steep grades. Diesel would be ideal and I wish it was available in the SUV's, always been appealing to me. How about a swap :)

What rear does he have? 3.73?

I've got a 6.0L with 4.10 rear...........it does the job but when I'm really loaded its going to slow but I also don't mash the gas, I drive the load.

You can allways go for a crew cab diesel duramax...

With 7 people going from Florida through the Rockies. I bet that would be a comfortable trip. Yeh right.

Ford did stop producing the Excursion a couple years ago, I think 04 or 05 was the last year? We recently picked up a clean low miles '03. It is sharp but only has the 5.4 gasser in it which is definitely not for towing. I would love to find one as clean as the one I have with the psd in it. My F-350 is the same model year; I get the same mileage as the wife's Excursion - when I am towing 10,000 pounds, anyway.

An aftermarket chip can free up some power in that motor. 40mph pullinh a 10000-12000lb trailer up a grade is respectable for a small block gasser.
Is the Suburban still in production?

If he is doing this on a regular basis its time to build a truck for the purpose out of a medium duty truck. A low pro truck with 19.5 wheels with a bus body type for people to sit comfortably. For one thing a medium duty will last longer you will have more power.

I bet that the Excursion your being referred to is in fact a Diesel model, in which case it would have plenty of pulling power. And so would a Duramax.

Why would you pull a trailer through the Rockies with a gas engine anyway?

Even If they offered a configuration for 7 adults to fit on a medium duty cab over truck. Would you want tor travel 12 hours a day across the country in that thing hell no.

Tim asks why he pulls a trailer through the rockies with a gass engine?

Because they don't offer a duramax in the Yukon yet.

Thought of building the engine a bit and the tranny? Another 50whp would be a noticeable difference, especially paired with tranny/rear work.

Just to be happy I'd say look for 100whp or another 125tq.

Oops Didn't see that he needed 7 people..

Can you build a gas engine up to gain more power and torque, while keeping it reliable? This Yukon is a tow truck so it will see hard miles. I know you can build that 6.0L into a hot rod engine but you wold never wanna tow with one of those.

i was pulling a truck on a flatbed trailer up a steep grade with my V6 1500, and it kind of struggled to maintain 45 MPH, not bad for a 6500 lb load with a V6 engine i thought. My friends excursion has the V10, and man that thing pulls thier livestock trailer likes it ain't even there. deffinately built for towing, plus it's the limited model, so it's very comfy.

Nothing runs great at 12,000 ft............less oxygen

Yes you can reliably build the engine without making a hotrod.

Things like a tuned PCM and new valvetrain. More money involved with boring it out. Tranny will hold more power but if you really start turning things up you need to take into consideration what will be absorbing that power and building those parts too. Check out www.gm-trucks.com for starters......theres plenty of sites, just do a search for "gm forums) or chevy, gmc etc.....

That is a bit of weight. However, pullin that through some of the slopes in the rockies at 40 mph is not bad at all. Have you ever driven the rockies? They're not your daddys little bump in the plains. 7-8% up to 11,000,12000,13000 feet is no easy feat for any vehicle.


The next best thing is the Ford Excursion but that has a terrible ride compared to his new Yukon's.

Resorting to a Ford is never a best thing.


Try a real people haulin truck...

that frieghtliner is awesome but i dont think it will haul 7 comfortably.

I think that the Excursion idea is best so far.

I was going to buy one until I ran into the Expedition that I have now.

my parents have a 02 excursion diesel with the 7.3, it is a comfortable ride.

I don't think he would ever waste money on a used truck. A freight shaker is cool and all but that would be a b!*ch maneuvering it in and around L.A. where he lives (everything there is compact with tons of people, its a nightmare at times with any truck & trailer) GM needs to offer the D max in suburbans and Yukon's, that would solve the problem.

Rhetorical question?

Was the 8.1 liter (496) big block available in the sub up until the most recent body style? Those motors had better power than the v10 gassers from ford and dodge.

I saw one of those for the first time the other day. It's just a stretched half ton chassis, tho, isn't it? Too bad you can't still get the Super Duty based Excursion.

Will the PSD be available in the E EL?
