I used to jack my TT a little.... My Kodiak had torsion suspension so I was sticking a jack between the wheels and lifting it about 2", just to relieve some pressure on the suspension...had the tires fully inflated...
But last Spring, when I got to the TT after the snow had melted, it wasn't at level, strongly leaning towards the door side... I looked under and one jack had laying on its side.
I suspect that the frost was severe and it pushed the ground up and the jack sideways.... and then the angle got too severe and the jack flipped.
No big issue I thought a 2" "fall",,,,,but the results were more severe than I thought
I'll need to find pictures, but the fall actually crushed the floor inwards... and my cabinets/stove and fridge shifted....
So with my new Jayco, I will not jack it up at all....even if the suspension is different and the construction better! I prefer changing tires or replacing suspension components over having some structural damages!!!!
