Offroad Limitations Of A Gmt800 Tahoe

I've had this '05 Tahoe for two months now and had it up on the mountain trails nearly every weekend. Here are a couple observations on it's offroad capabilities.

 

I think it's biggest limitation is it's weight. There are just some things that it can't pull it's fat ass up and over. Power isn't an issue, it just can't get the traction to climb up a steep rock if you're already on a steep incline.

 

The second limitation would have to be suspension travel. It spends way too much time with one or more tires in the air.

 

However, all said, I'm very pleased. It gets through some impressive spots and over some pretty rough obstacles. Dragging it across the skid plates is no problem, and it continues to run just fine while laying on it's side (just a little smoke). :lol:

 

Another HUGE plus is the hydroboost brakes. I've had the engine die twice while coming down a very steep slope. Brakes held just fine so I could put in neutral and restart it.

 

I'm also thankful for a real bumper instead of the plastic wrapped GMT900, even if it's a little soft. :lol: (that just means that it bends back easily though) :jester:

bigger tires my friend

 

That would be ideal, but I'm pretty much limited by my stock wheels and ride height. New wheels, new bigger tires, and a small lift isn't in my budget just yet. :jester:

 

It's fine, I don't get pissed if I can't make it past something. I actually like finding places that are beyond it's limits.

Tire traction is not the Tahoes fault and its not a rock climber in stock form. :jester: The motor died probley because it sucked air when the fuel moved away from the fuel pickup in the tank, thats why you should have a full tank of fuel when offroading.

I always start with a full tank of gas.

 

My point was that these tires could pull a lighter vehicle up and over some of the obstacles that have stopped me. It's not for lack of trying on the Tahoe's part. I can ride the brakes and get all 4 tires smoking, it's just too heavy to climb up a straight rock edge if you're already going up a steep incline. :jester:

If you're having traction issues, I wouldn't necessarily go with bigger tires, just go with a more aggressive tire, with a softer rubber compound.

 

Also, how much are you airing down your tires?

I go down to 12-14 psi. Traction isn't really an issue. It gets me through some pretty rough spots. Some of the places that stop me, a Tahoe probably shouldn't be attempting in the first place. :D

Satori I could not agree with you more. Every time I have gone off-roading in my Silverado weight is my worst enemy. Trucks just too damn heavy. Dont get me wrong, it sure is fun, but its a P.I.T.A. to see a 4 cylinder Wrangler go through/over something with ease and my truck sinks so I have to power out of it or get towed. :cheers:

Yes, weight is our worst enemy. As well as the width. I would love to have a Jeep, but I carry too much stuff and they just don't have much back end room. Also I am a bit large, and the Jeep front seat is a bit tight. A Defender is nice, but oh... the cost $$$. A Discovery probably would work well.

One of these years I'll probably get another vehicle to augment my Tahoe. Not anytime soon though.

Nah, for me at least, I feel that I've chosen the best possible vehicle for me this time around. If I wanted a really serious off roader, I wouldn't have bought a Tahoe. :jester:

Truck's wheel base is too long for rock climbing, weight is too heavy, and a pickup's weight distribution is completely wrong for it. Your better off buying a cheapo jeep and towing it with the truck. :jester:

Just like people who buy a jeep and then expect it to pull 8,000lbs. It wasn't built for that, if a jeep and tahoe hooked bumpers the tahoe would drag the jeep around pretty easily.

Damn right it would! :cheers:

 

I know what you're saying.

      Is the 6.2L L87 in a 2026 Sierra 1500 ok?

      By asilverblazer · Posted

      What meaningful corrections were done to fix the "machining errors?"   I bet nothing, because the 6.2 is soon to be obsolete. Why would GM implement any fix let alone an "expensive one?"   Until someone can provide any convincing information that GM did ANYTHING to correct the engines - the 6.2 is no for me.    Which means keeping the 2016 Denali longer until the next generation (6.6?) proves itself.

      If my father took a Sunday off. We did the Sunday drive. Usually stopping at a Geno’s for dinner that we eat in the car. Six of us with my little sister up front. It was always a Buick growing up. In New Jersey you couldn’t get lost. Not like Texas.

      I suppose I am Atlas. It can always be worse, eh?   I had a friend once that rolled one payment into another until he was paying the price of Benz for a 10 year old back marker. Wouldn't be often you start a new payment the month following your old one.

      I still enjoy the drive   Some people fish when they retire; some golf. I drive. We've lived in the same general area now for twenty eight years and I'm still finding at least monthly some sweet quite little road to explore. When I tell the Mrs. I'm heading out for coffee she knows that could be a five hour event. Often she even goes along.    I like finding new rural routes used mainly by the locals that start nowhere in particular and end the same way. Many in the area of that type are narrow paved and twisty, hilly and run through field and timber. Often along creeks or wetlands. Unfarmable areas of great natural beauty.    After years of this type of exploration they start to fit together. One ending a mile or so from another and you start threading together a new path from a unfamiliar place to a new adventure. Sometimes to a little town of under five hundred that used to be something before the Interstate or some railroad or US highway bled the life out of it that has a small dinner with the greatest slice of pie you've eaten since grandma made her last. A little village museum or library or even a town square park with grand old oak, walnut and Osage orange trees to sit under while you sip you gas station coffee and chat up some locals.    Often they are full of stories about the main streets more interesting buildings and the who's who of the area. Sometimes some hidden attraction or unseen history. Our area is full of old coal mines.     A younger self used to do this going cross country by motorcycle. Only a general area as a destination with no time to get there and no time to be back. Sitting at days end in a 10 unit off the main highway motel under a Sycamore tree yacking with the owner or his one semipermanent guest while I adjusted valves or the chain. Always a wave and a shout "Hey there stranger"!  It's how I came by my love of old Brit iron. There is no such things as a ten minute gas stop when your on a Enfield or a vintage Triumph. Same being true of old cars.    If you take the time to really look I've found everywhere is someplace interesting. Illinois or West Virginia. Different and yet the same.    People are in a more relaxed mood and will talk about anything and everything and if they like you there may be a cupp'a or a lemonade and a sandwich in it. 😉
