The trailer is a 2013 351RLTS. The factory specs are 12,000 pounds total and 2400 on the pin. I have no idea how much weight is on the legs.
The rep from Atwood told me the jack is rated to 5500 pounds.
He put the gearbox on today with the camped hooked to my truck. When he was done, he raised the jack until it started to raise the truck and called it good. I was standing there. It looked okay to me. I guess the jack runs into problems when it becomes responsible for all of the weight.
The jack was installed on the frame by Lippert. I learned that much last week. Jayco gets the frame from Lippert with the jack already there. When they are mass-producing those frames, how can they really know if the jack they are putting on there will be adequate for the trailer that is eventually built?
As soon as the warranty is out on this thing, I think I will install a two motor system. The one from Bulldog looks pretty good. I am hoping that somebody from Jayco will agree that this jack is inadequate and that they'll spring for an upgrade. I'm not holding my breath on that one.
Here is the Bulldog I've got my eye on:
