Levelling with Scissor Jacks
I know I'm going to get flamed, but I replaced the (4) OEM single arm stabilizers on my Trail Cruiser 30 ft travel trailer with (6) 24" scissor jacks. I experimented with lifting excessive weight with...

BTW those scissor jacks are very poor lifting jacks that have a lot of free play in them and they to will buckle easily with only modest movement applied to them… the lifting part in their claims are more marketing than fact…
That's why people buy heavy duty ones that are rated for twice what you want to lift. Actually more like 5 or 6 times. And if you have six 7,000 lb. jacks lifting an 8,000 lb trailer that's only 1,333 lbs each which I think even a light duty scissor jack can handle let alone one rated for 7,000 lbs.
As far as calling him silly like you did because you don't agree with him well I don't agree with you either but I won't call you silly. I'll just state what works for me. I've been doing it for 2 years and mine has not fallen apart and neither will his. Most all trailers are supported at four or 6 points on the frame by the springs that attach the axles to the frame and the remainder of the frame is back there bouncing up and down cantilevered out as people go speeding down the highway at 75 or 80 mph over railroad crossing and big bumps in the road without any support and are no worse for the wear.
The way you do it is you jack it where the axles are attached to the frame at the center of the trailer on each side. You don't jack it at each end. Then use the stabilizers at each corner to stabilize it. All the weight is carried by the frame right where it's being supported anyway by the springs.
