My thoughts on this is that jacking a pod level from the four corners is creating strain on the pod's frame that it might not be designed to handle. Depending on the out of level situation, and a stronger stabilizer/jack, you might just be tweaking the frame. I know that I've read (somewhere, maybe on this forum?) where people have used the scissor jacks to level their pod, only to find that it's caused problems with the door frame.

Putting it another way, a stronger jack might be able to level your pod, but the frame might not be able to handle all that stress all the way out on the corner.

I had bought a few items from a company via Amazon (30 ' 30a extension) and it came with a little catalog. On the front page was a selection of stabilizer jacks. They looked a bit heavier duty than the ones on my pod. I did not see a price. But they had jacks there rated for 5000 lbs, would in theory lift the whole pod.

And I wondered. What is to keep a guy from ordering a couple of those, mounting them on the front, using them to level. Then run the others down to stabilize. Keep the old ones for spares?

Wouldn't that be easier than this mucking about blocking wheels?

I'm probably wanting to defy some cosmic rule of camping here.
