How to Determine Trailer Tongue Weight for Selecting a Powered Tongue Jack
Question:
I have a KZ 20foot trailer with weight distribution and tow it with a 2015 Tundra. Is there a way to determine or estimate the load of the truck and tongue to size the jack?

The easiest way to measure your trailer tongue weight (TW) is to use a scale like the etrailer # e99044. There are other methods outlined in the linked article or you can simply take the truck and trailer to a truck weigh station. In general, a properly loaded trailer's TW will be about 15-percent of its gross weight.
You'll want to select a jack based on the trailer's heaviest weight condition, in other words when it is fully loaded. This will let you select a powered tongue jack with enough capacity and enough safety margin. A jack will last longer if it is not used at its maximum rating, so you want to choose a jack with capacity of several times the trailer's actual TW.
You can use the linked page to view all electric tongue jacks. You can choose weld-on or bolt-on installation and whether you want a foot on the jack tube by clicking on the filters.
The Lippert # EJ-3520-BBX is a powered jack rated for 3500 pounds of tongue weight, and easily bolts on.
