Replace flat tire with Torflex suspension
We purchased a new to us 19 Flagstaff 29RKWS TT in April with the Torflex axles. We are using it on and off in the driveway as we have some remodelling going on in the house. Have taken a couple close...

I always prefer to jack under a section of the frame rail, near the flat tire, that is well reinforced.
If you jack does not have enough lift, build up UNDERNEATH the jack with blocks of wood placed perpendicular to the jack base. Worst case you may need 2 or 3 layers.
Remember, scissors jack start to get unstable once the are past about 50% of their maximum lift.
Not cheap, but this has a built in jack stand so no chance of hydraulic failure injuring someone. Powerbuilt Unijack - 6000 lb. Capacity
Why would you jack up the frame and have to lift it twice? as high? That makes no sense and I'd like to see how that is accomplished with any bottle jack including the combo contraption you posted. Barely enough travel in a typical bottle jack to get a tire all the way up lifting under the axle, much less taking the load off the suspension as well.
OP, I currently have 2 different tandem axle trailers with torsion sprung axles. I jack them up from the axles every time and have with virtually every other trailer and vehicle if it's possible to do.
Put the jack directly under the axle as close to the outboard end of the axle as you can. Just like you were thinking.
You are right on the ramps though and ramping the good wheel up to lift the flat one works even better on a torsion axle than it does on a leaf spring axle, as the 2 axles aren't connected by the pivot on leaf spring axles, so one doesn't have to ramp up as high to get the flat off the ground.
