Answering "How Much" Questions

Sorry for this long and wordy post... I am looking for some feedback on a little project I have been working on today. Kind of a sick day for me... so I have taken the down time to try and be productive.

One of the questions many people ask in the TT, Fiver, and TV's forums is how much can I tow? Really this is two questions in one.... How much you can tow (trailer weight) is directly related to how much can you carry (payload).

I have created some charts, in an effort to help some out with correctly answering, how much can you tow and carry at the same time.

After one arrives at an understanding that their vehicle must not only tow but must also carry the tongue/pin weight... the next question is... how do I know how big of a trailer I can tow without overloading my TV? After all the tow rating is often MUCH higher than how much payload the truck has available.

Now the charts, and I wanted to ask the forum if these make sense.. if they are useful... or should be scrapped?

Basically, you take your available payload and based on the rule of thumb 13% tongue weight for TT's or 25% pin weight for fivers you get an APPROXIMATE max trailer weight... of course if your tow rating is lower than what the chart says is a match for your available payload or your GCWR is lower then the LCD rules in this number games.

Here are the charts

How to calculate available payload



Travel Trailers



Fifth Wheels



Are these useful, worthless, can be improved?

Thanks for the feedback in advanced.

  • Thank you both for the feedback. If I can do anything to help people think about safety then I have accomplished my goal. RV'ing is supposed to be fun and relaxing.

    There is much more to towing than just weight...but if you start behind the 8-ball then you are playing catch-up through the entire RV'ing experience. start out right...match the truck and the trailer together and you will be well on your way to that cold one under the awning.

    Thanks!

  • You provide an interesting way of looking at tow limits. You bring some reality to the often ridiculous concept of half ton towable fifth wheels. From your chart if the fifth wheel weighs 8000 pounds (and most are heavier than that often by quite a bit) the payload needed to accommodate that is 2000 pounds, rarely found in a half ton when people, tools, and all the other stuff is also added against payload.
