Help! Towing Advice Needed

[Phokaioglaukos]

I think Graham has put his finger on it. The length of the trailer has to be appropriate for the wheelbase of the tow vehicle. For example, the Toyota Sequoia has the same engine and powertrain as the Toyota Tundra giving it the same towing capacity (around 10,000 lbs.), but with a 122" wheelbase it cannot tow as long a trailer safely as the Tundra with a 145" wheelbase. And a F250 short weelbase has a 156" wheelbase.

Note that a 24' trailer will be around 31' from coupler to tail (the way the first table woriks) depending on design. You'd want more than a Tundra for that trailer.
