Ask The Triton Expert:
"Why are some accessories not standard on a trailer like a tongue jack?"
Some trailers do have tongue jacks standard but they are usually on larger three place trailers or trailers with GVWR's over 3000 pounds. Most smaller or lighter trailers are easier to move around off the hitch with out a tongue jack. Due to personal physical limitations, added cost and/or style preference, you might or might not want to have the tongue jack or other accessories standard. Generally if it is not really needed to be able to use the trailer, an add-on or extra comfort and ease item is usually an accessory to a trailer.
This is also true for many other accessories which are optional because of the many varying needs of consumers across the US and Canada where Triton distributes its products. The standard trailer then becomes something you can mold into the trailer that you want with the options that works for your hauling needs.
