Re: Can my 1999 Yukon Denali Tow my 24" Boat

I dont want to get into accident , thats why i ask people for input..

plus i dont want to be in youtube for being an idiot..

I ask the dealer, and ask them about information about my SUV and what is my plan. they have told me its risky but it will be able to pull it no problem.

. but he recommend not to tow with it because if the SUV is lighter than the boat and to be safe just to purchase another powerful SUV and i should not tow with the older SUV.

that's stupid. i have pull this boat with a V8 5.7 L Toyota Tundra and it was no problem at all..

The Toyota V8 5.7 L.. my is a 5.7L V8

I think he just want me to purchase a new SUV. LOL

-----

If a Toyota Tundra With V8 5.7 will pull the boat no problem at all. why can i pull my?

i also assume my SUV and the Tundra weight will be about the same.

I dont see why my SUV will not be able to tow it?

Please tell me iam wrong and why..

Iam not trying to be a smart ***. but i been searching information about The Tundra spec vs my SUV Spec. i just dont see why i cant pull my Boat.. the only thing i will need before i tow my boat is a Helper Bag for the rear suspension

Have you put the boat onto the SUV yet not saying to tow but just to get a look at how squatted down it may be. You may find that just by putting the boat onto it and taking all the weight off the boat jack that it is close to bottomed out as it is let alone towing the thing. If the trailer brakes are all working as they should that part should be okay but. Compare the differences between a 1/2 ton and a 3/4 (older like yours) the axles, brakes, drivetrain is way more heavy duty and more geared to this type of hauling. It seems like the older 1/2 tons are fine up to about a 20' boat, gas, gear,tandem trailer. Too much above that and it starts to get dicey, can it be done yes but hang on to your butt if you are involved in a crash. Need to get the boat and trailer weighed as it would be if going to the ramp, then go from there.

Find out what gear ratio your Yukon has. Hope for a 4:10. If it has a 3:42 you are going to struggle. Gear ratio has a major impact on overall tow rating for the truck. If you have the owners manual it should list towing capacity for each ratio.

That vehicle has a 3.73 at best, but is likely a 3:42.

Seriously, if someone gets hurt or you have property damage, or you get a citation, and you have to defend yourself in court, do you think anything posted in this forum saying, Ya Go for it dude!!! will help you if you have exceeded the manufacturers towing specification?

please back this statement up with a case where this has actually happened. the part about exceeding man. limit.
if your at fault in a accident chances are your going to get a ticket no matter what. you can be driving empty and get a ticket for that matter.


i read this all the time but here in nevada, utah, colorado, and wyoming. i have yet to read, see, or meet any one issued a citation other than truckers that fail to purchase the proper over weight, size load permits and get caught.

this is poplar statement every time this subject comes up and i realy am curios to know if its urban legend or fact based.
i know all the pu and trucks i have used over the years have load plates in the drivers door post or glove box but have never had a law enforcement officer look or ask to look at one ever.never. not once

Your video actually supports that it is ok to tow over the manufacturers towing specification. The video shows an old minivan towing a huge boat, and doing it just fine.

Now the driver did get too close to a parked car and hit the mirror on the parked car. What does that have to do with using a small vehicle to tow a huge boat? Same thing could have happened if the guy was using a semi to tow the boat.

Just to be clear, I'm not advocating towing more than you should. Just pointing out that the linked video shows an old mini-van towing a huge boat, and doing just fine with it.

Your correct man.. i know people should never go above factory Towing capacity. but if a V6 Mini Van could pull that. dang. i should could pull my . specially i have a 4x4 LOW for pulling it off Water..

i will experiemtn in about 1 month after i have install the Helper Bag for the rear suspention.. i will PULL the boat up the HILL from Complete STOP going up HILL from my house first.. if the SUV could PUll that BIG MAMA off that BIG heLL i sure will be able to PULL it off the DOCK.. my HILL is bigger than ones in the DOCK. WAY WAY BIGGER.

You will have no problem towing that boat with that truck I tow my 24ft Four Winns Lib. this is a heavy boat at 4300 dry boat alone with my Toy Squioa we just take it ease and are never in a rush I have no probem. Stoping can get a little rough you can sure feel that boat behind you we have the same trailer brake system that you have.

Re: Can my 1999 Yukon Denali Tow my 24" Boat

thats my 99 pu but from the front you cant tell it from my 01yukon xl
they are both 5.3, automatic, 4x4, 3.73 rear end with the pu having a possi. my son had a silverado just like the serria, with 4.11 gears. in the end the 4.11's didnt realy make that much difference.
the boat and trailer your looking at was scaled 3 times with the heavy being 7500 and the lighest 7300. the boat is 24'8" from tip bow to back of swim platform with the drive hanging out a foot or so more

towed quite a few miles this way with both. shortest trip is 160 miles and longest is to lake mead at 760 miles. both one way miles.
i dont leave home in colorado and go any where with out going over a mountain pass.

did trade this pu this spring with 170 k miles but had nothing to do with towing this boat or having any trouble with it.

NADA says your boat with twins dry is 4200. Add trailer for 1200 plus 1000 lbs wet and ready to go. That's 6400. You've got disc brakes which helps greatly. Make sure you maintain them. You're right at the top of the TRAILER towing capacity of the Yukon. There's another capacity tag on your door sill that says GCVW (gross COMBINED vehicle weight) That means truck and trailer. That's where you and your crew and stuff ride. The thing to do is to drag the ENTIRE rig across your local truck stop scale and see where you're at. I'm betting no worries. I tow about 6200 lbs with a 5.3 with a 3:73 in an Avalanche with a disc brake trailer with NO issues. The Avalanche is longer wheel-based than a Yucon and rated at 7200. But I never feel pushed or overloaded especially with an equaliser hitch which I'd recommend in your situation for added stability. You've got plenty of brakes, plenty of motor, just add the right hitch that allows for motion of the surge brakes but helps make up for a little less wheel base.
