Towing Load Question

Hello,

I’m looking at buying a used trailer for going camping with the family this year possibly a hybrid trailer since they’re light weight. I’ve never owned a trailer before so I have a few questions on how much my truck should be able to tow. I currently have a 2006 Toyota Tundra double cab 4x4 which is not quite a ½ ton truck since the Tundra’s became a half ton truck on the 2007 model. I’ve looked online a bit on how much I should be able to tow but have a few questions. Any feedback on this would be much appreciated as I am not sure about my calculations or understanding of how this should work. I called the dealer and they did not know what the GCWR (Gross Combination Weight Rating) is for my truck so I tried figuring out the below instead.

When I look on the sticker on the door of my truck it says the below.
GVWR (Gross vehicle weight rating): 6600lbs

When I look on cargurus.com they say the maximum cargo & towing payload would be 1,635lbs. I’m assuming they got that from the GVWR of 6600 – the vehicle weight of 4,965 which equals 1,635lbs.
If that is correct then if a trailer weighs 5,000lbs loaded would that mean 10-15% of that weight would be on the tongue I’ll say 15 which would equal 750lbs. Then if I had three adults with combined weights of 500lbs that would be 1,635 – 750 – 500 = 385lbs left over for storage and other items. I’ve heard I should have a 10% buffer so I’m not at the max GVWR of 6600lbs which would be 660lbs so I would be over that limit.

So if I took the GVWR of 6600 and took of 10 % of that then I would be at 5940 then if I subtracted the vehicle weight of 4,965 that would be 975 then if I had three adults with combined weights of 500lbs that would take me to 475lbs which would mean the maximum trailer weight I would want fully loaded would be 3,000lbs since 15% of 3,000lbs is 450lbs which would bring me in at 25lbs under capacity. Does this make sense? I don’t think they have trailers that light as far as I know most of the trailers might be 3,000lbs unloaded at the lightest end but loaded I would assume it would add another 1,000lbs or so.

I’m basically just trying to find out what weight I should not go over for pulling a trailer. Thanks for the help it’s much appreciated.

Thanks

  • You don't need a 10 percent buffer, that's hogwash. Limits mean just that, "the limit". Safety factors are already built in to the limits. On the other hand, you shouldn't exceed the limits either. Having said all that, you look like you got a good handle on the payload number, what it means, and how to figure it.
    There should be a yellow payload sticker on the door of your truck, it will say something like "the weight of cargo and occupants should not exceed ________". That is the number that you should be using instead of the "1635".
  • Your first way of figuring is the right way, and a 5k lb trailer would be about your maximum, if you truly have a payload of 1,635 lbs.

    In 2006 there should be a yellow and white tire loading sticker on your driver's door panel. This should read the total payload of people and gear, and of course WDH/tongue weight would be included, not to exceed XXXX. If this is 1635 you are good to go with the 5K max trailer.

    It is nice to have a buffer, and not tow at the very limit, but not really necessary IMO. Many tow way over limits, don't know any better/don't care!

    You are wise to do the research, and ask questions!!
