When integrating a tow vehicle with a trailer, either a fiver or travel trailer, add the GVWR of the trailer with the GVWR of the tow vehicle. If they add up to more than the GCWR of the tow vehicle it’s a bad match. The only solution is to pick a lighter trailer or a bigger tow vehicle. The same applies to a self contained unit and a towed unit, either four wheels down or on a dolly.
