Assistance needed please

I am a newbe lookng for a small-ish double axle TT that I can pull with my SUV.
I have a 2014 Jeep Grand Cherokee Limited with a 290hp v-6 engine, full tow pkg. 4x4
What I need help with is determining how much trailer I can buy and still be safely under the numbers. According to my owners manual I can tow 6,200 lbs with a maximum tongue weight of 620 lbs. the door sticker says front gawr is 3200lbs, and the rear axle gawr is 3700 lbs another sticker on the door panel says combined weight of occupants and cargo should not exceed 1,050 lbs. with all these numbers it's easy to get a little confused. I know this is an old problem, but any help would be greatly appreciated. I sure would love to hear from people with experience because I know there are things that extra weight such as batteries, LP tanks, hitches etc.
It's intimidating for me and I want to be safe always...

  • You need to find out the GCVWR- Gross Combined Vehicle Weight Rating- the GVWR doesn't directly relate to the tow rating. Then you weigh the vehicle, subtract that from the GCVWR and you get the maximum you can tow.
    Manufacturers often figure the trailer weight using a bare bones stripped model, in order to get the highest possible number (the classic was a Chevy Astro van with a 5k rating, arrived at using a bare cargo van. A standard finished van had an actual capacity of under 2k).
  • Thanks Brian,
    That is kinda my plan, to go with something small-ish and be way under any weight limits. I just wanted to get an idea of maximum so I don't run up to it....
    What I've been looking at is in the 18 to 21 foot range....
  • Thanks Dave for the info. It says on the window sticker on my Jeep that it has a class IV tow pkg.
    I pretty much figured that cargo weight would include the tongue weight. And I guess the weight of the batteries and full LP tanks would have to figure in there somewhere as they are sitting on the frame near the tongue. And the WD hitch weight has to be figured in.. Perhaps the only way to know for sure is to load it up and take it to the scales.....
    If I get close on the weight I'll just leave the wife home.....lol
  • Go as light as you can and you will be a happy camper. Because you can tow 6200lbs doesn't mean you have to. Can you find something in the 4000-5000lb range you like? What about the 3000lb range? Even better.

    Figure out the features you are wanting and start looking at that. Don't start looking at weights and such and then try to figure out something in your max range. Once again, the lighter and smaller you can go, the easier and more comfortable you will fill towing it. Plus the smaller it is, the more options for campsites you will have.You can fit a 20' TT in a lot more campsites than you can a 30' TT.
  • I think that you are mixing apples and organges. Look at this website for some clarification.

    Forget about the towing deal for a second.

    I looked at the spec for your vehicle. It says that the GVWR is 6500 pounds. That is the total max weigh that the vehicle is rated for. which includes a dry vehicle weight of 4545 pounds, a full tank of gas and fluids, and 1050 pounds of passengers and cargo. This will include the tougne weight of a trailer. So if you can carry 1050 pounds of cargo and people and your tongue weight us 620 the numbers are 1050-620 = 430 pounds of cargo and passengers in the jeep.

    You can distribute this as your see fit as long as you don't put any more weight on the front axle than 3200 pounds or 3700 pounds on the rear axle.

    How to get to the towing capacity. According to the specs you can tow a trailer that weighs 6200 pounds with a tongue weight of 620 pounds. The tongue weigh would have to be figured into your GWAR on the read axle.

    Finally you will need to check the hitch rating . The hitch that is installed on your Jeep will determine the maximum weight of a trailer that you can tow. A class III hitch is rated for a maximum weight of 6000 pounds. I would bet that you have a Class II or III on your jeep. I will let you look up hitch ratings here
  • The limiting factor will be your payload (1050lbs). You need to figure out the weight of all your passengers and cargo that you put in the SUV first. Keep the cargo to a minimum by putting as much as possible in the trailer. Once you know the weights going in the SUV you subtract that number from your payload. What's left is the available payload for the hitch and tongue weight.

    For example, if your passengers and cargo weight 450lbs combined you have 600lbs remaining for the tongue and hitch weight.

    Most trailers average between 12-15% of their loaded weight to be carried by the tongue and WD hitches are around 75lbs. If you were on the low end at 12% it would mean a loaded trailer weight of around 4400lbs.

    600lbs - 75lbs = 525lbs
    12% of 4400lbs = 528lbs

    Some of the weight will be transferred back to the TT through the use of a WD hitch but you'll be pushing the limits with a TT over 4500lbs loaded weight in this example. Just 2 light passengers you might be ok up to 5k.
  • This means that is the trailer you want weighs 6000 loaded, and the pin weight is 600 lbs, you can have up to 400 lbs for passengers and cargo, hitch etc.
    I would recommend sticking with a trailer with 5000 or less gvwr (loaded weight, with that suv.
