    Default Towing advice with my 2011 2500 Suburban

    Hello all,
    I bought this sweet rig almost a year ago with the intension of pulling a boat with it. Well I think I've finally found the boat and I'll be going out to Lake Havasu to look at it next weekend. If I like it, I'll be buying it and towing it home. It would be a 26' day cruiser weighing in at 6500-7000 lbs.


    The burb is totally stock. No tune, stock tranny cooler, typical 2500 stuff. I've not towed with this rig yet but I'm expecting it to do a great job. Obviously I'll be in trailer towing mode, but I'm wondering what other things you guys would recommend? How fast should I try to take the Cajon Pass? How many RPM's can I safely run at going up that grade? How hot can the tranny temp get before I should be concerned? When on the flat, is trailer mode all that's needed? Anything else you can recommend?

    Thanks!

    Your questions regarding speed, rpm, etc.....tow mode will do whats best.

    Personally, I would be more concerned about stopping that 3+ tons.

    ^ Well that's why I bought the 3/4 ton suburban. It has the beefier drivetrain, including brakes.
    26' boats are pulled all day long to the river these days. What else is one to do?

    You can rev those engines pretty high, so I wouldn't be too worried. Your 2011 has the 6 speed, so I'd imagine you might be at or around 3500-4k going up those grades in 4th/5th gear while towing. Don't let the trans get over 240 degrees for extended periods of time.

    Don't be afraid to drop gears and rev the engine when climbing those grades. It was built for it.

    Good luck and congrats on the new boat. Post pics!

    Thanks Eddie. Exactly what I was looking for. I'll post pics if the deal goes thru.

    Any other suggestions are certainly welcome.

    Thousands of people tow with this vehicle, don't tow in overdrive and stay above 45 up the grade. There is very little difference in 45 and 75 up the grade when it comes to time. I would double check the trailers brake system.

    Default Towing with my burb for years.

    I learned some things about towing with my Suburban. Always use tow mode. Never tow in O/D if there is much of a grade. I usually tow in high gear without O/D unless the grade gets steep and starts lugging the motor hard, then I pull it down to get the motor to about 3,500 RPM. The most important thing and I see another person addressed it is, don't fear revving your motor. The sweet spot in the motors power band is about 3,500 and the first time you are towing when you pull it down and start up a hill at 3,500 you will really be impressed with your Suburban. They have a great brake system but when you tow a lot they will eat pads about 30% sooner than normal. I also learned to use the high dollar pads on the brakes, they will live twice as long and I pitch all the rotors every time I do my brakes any way.

    Thanks for the comments, guys! I appreciate the input. I'm told the brakes are pretty bullet proof on these 2500's, so I'm not too worried. Also, I have trailer brakes in the suburban, so that helps. Pretty sure this vintage of boat doesn't have them on the trailer, but I'll look into getting them installed.

    i can tell you exactly how to deal with coming down the pass.#1 make sure you have good trailer brakes.#2, make sure you have good trailer brakes. I have electric over hyd, crest the top at 65, and I keep the truck in 3rd, if your in trailer mod, every time you hit the truck brakes, the damn thing will down shift to way too high of rpm, hence, I keep my speed down with the trailer., there is only about a mile that things get sketchy
