    I wouldn't recommend towing more than 5000 lbs with any short wheelbase truck........And if you do tow make sure you use a quality anti-sway/weight distribution set up.

    Don't tow in OD, and install a big aftermarket tranny cooler.

    Towing weights are generally limited by the following factors:
    Hitch rating ( class 1,2,3, 4, ect)
    GVWR tounge weight should not exceed the axles or the hitches tounge weight rating.
    Tires load rating
    Your engines horsepower rating x 35 usually equals the heavyist trailer you should tow; EX : 210 Hp x35= 7350 lbs.
    These are the general rules most go by.
    They dont say a specific towing weight because there are so many varibles and if they specified a weight and something went wrong GM would be liable. Thats why the manual states: " This vehicle was primarly designed to carry people and cargo"

    My 89 blazer has the Tow package and I tow quite a bit. I have a 18' ski/fish boat I tow all over the west and I'v towed travel trailers and other stuff.
    The heavyst thing I ever towed was a 1953 ford F100 on a car trailer. It prolly weighed around 6000 lbs. I towed it about 400 miles. I took it easy and had no problems but I think that was the Max I would ever tow with a Blazer.
    Trailer brakes and an equalizing hitch are a must have on any trailer over 2000 lbs

    I have a 91 and tow a 22" boat that goes about 5500 when fully loaded. Thats about the max I would pull with it. Have to get a longer wheel base.

    GVWR means gross vehicle weight rating. Unladen weight is the weight of the vehicle. Subtract the unladen weight from the GVWR and you have the amount of weight that you can legally tow or carry with your vehicle. Yes, your vehicle might be capable of towing more but not legally. If for some reason you are stopped by a highway patrol and he decides to have your vehicle weighed and you are overweight then you will not be allowed to continue and you will receive a citation as well.

    Actually you are correct. That is the amount that you may carry in your vehicle. The weight being towed depends on the type or class of hitch you have and also the size trailer ball. Then the trailer will also have a weight rating as well.

    You both are partly right. The GVWR is for the truck only. Then there's the CGVWR or Combined Gross Vehicle Weight Rating. The GVWR of my Peterbuilt is 51,000 but the combined rating with my trailer is 80,000.

    Regarding GVW and trailers: The only weight from the trailer included in the GVWR is the tounge weight.Tounge weight is the trailer weight that is resting on the hitch So this means that the tounge weight and the combined weight of the vehicle,passengers, and cargo should not exceed the rear axel's capacity. tounge weight can vary depending on how the trailer is loaded.
    Loading a trailer tounge light can cause the trailer to sway side to side badly and go out of controll.
    Loading a trailer tounge heavy causes undue stress and wear on the drive train.
    I cant rember all the weight specs for the different hitch classifications but i Know that the Tounge weight limit on a class 3 hitch is 750 lbs and max trailer weight is 7500 lbs using an equalizing hitch. The weight limit is around 1500lbs less if you are not using a equalizing hitch. The class3 is the largest hitch you can put on a K5. The class 4 is a 5th wheel hitch.

    I tow a 23' RV with sway bar, weight distribution bars. My trailer weighs 5200 lbs. That is about as long as I would go and as heavy as I would go. 350, 700r
