My luck: I contacted the "Atlanta DTH Inc." and they were kind enough to reply. They were in the RV accessory business but when the RV business went into a slump they got out of the RV accessory business. I can't even find any info as to the ratings for this jack but obviously it is not rated for my cargo trailer. Come to think of it, the only time I went over the scales to weigh this trailer, to satisfy my curiosity, the trailer and contents were a bit over 6000#. I have no idea of the tongue weight. Lesson learned. Does anyone with a kids "little red wagon" need an electric tongue jack for it?
