I had a flat on the trailer last week, small Pop Up, and was able to change it by myself using the jack from the truck. No problem, just jack up, change tire and jack down. But it got me a thinking....
What size? In theory a 6 ton jack can lift one side of a 12 ton trailer.. However in practice.. The trailer may be overweight or the rating on the jack a tad "Generous"
I would go with the Trailer's GVW sticker.. Whatever the trailer is rated as max weight.. A jack in that range should do it.
Example. On my motor home I use a 12 ton, the motor home is rated to be no more than 22,000 pounds (11 ton)
