The rule of thumb for estimating a tongue weight is 10-15 percent of trailer weight. So your 14,000 pound trailer would have a tongue weight between 1400 lbs and 2100 lbs so any trailer jack rated over 2,500 lbs would be sufficient to lift the trailer's tongue however I recommend a higher capacity and high quality designed jack because they tend to last a bit longer. The most common reason for a trailer jack to stop working is because of friction that breaks down the gears and and over-extension.

I recommend the Stromberg Carlson # SC63VR which is rated for 4500 pounds of lift. It also has an automatic stop feature that will not allow the jack to over extend and become damaged unlike standard jacks that allow the jack to extend beyond the recommended height which puts a lot of extra stress on the gears. This jack has 23 inches of lift, plus 5" additional with the drop-foot.
