straight line winds moved camper, must have twisted jack

We had our TT parked at a friends barn, 2 hrs away, where my husband was using it as a "home base" for an out of town job he was working on. He came home for 2 weeks and when he went back, the camper appeared to have been slightly "tisted/shifted" from its original position. They had had a bad storm with straight line winds. The jacks were out of placement and in the mud. He and my dad were trying to get it repositioned and the jacks back on their "pads". When they cranked the tongue jack, it broke and the tongue crashed down. They used a car jack to get the camper set back up and realigned and everything seems to be ok and working fine. Except now of course, we need to replace the tongue jack. As I am searching online for a jack, I am overwhelmed by all the pictures, none of which look like ours. How do I know what I need? I dont see anything that tells me a type or size. I have a 2006 Keystone Hornet 27B
