Jack Stand Reccomendations
From what I've read, I would be looking at 6-ton jack stands. Does that sound about right? THX

A bottle jack, especially one that has 18" of travel, can tip over.
The small base of the bottle jack is not a large enough footprint to absorb any shift in center of gravity as the ram raises the load higher into the air.
About 25 years ago, a bottle jack tipped over on a motorhome I was working on. Fortunately, I already had jack stands pre-positioned in place, and plenty of them.
Floorjacks, on the other hand, are like rolling pyramids, with a wide base and a very long foot print contacting the ground. Floor jacks are not as vulnerable to tipping over as the center of gravity shifts with height changes.
Especially offset height changes, where the jack is being applied to one frame rail, which tilts the truck more the higher one lifts.
To avoid tilting the truck when raising it, consider using two floor jacks simultaneously, one under each frame rail (or axle perch, etc).
With two floorjacks, one doesn't need a 4 ton floor jack. My floor jacks are only rated to 2.5 ton (with 31.5" of lift), but since I use them two at a time, they provide 5 tons of lifting power, evenly distributed under the truck, with not only a wide base and a long footprint per jack, but the two jacks used together helps prevent any tipping of the truck, and thus there are no shifts in center of gravity, and no twists tweaking the body seams from racking.
Takes two to tango:
The red steel tube blocks have a 1" steel dowel pin through their center that interfaces into the floor jack in lieu of a jack cup:
(F-550 shown. Pickups have thinner axle tubes, especially in the rear, so follow Ford's recommendations for raise and support points, as shown in the owner's manual)
Six ton jack stands:
Floor Jack range from as low as 5" to as high as 31.5".
While these high lift floor jacks are only rated to 2.5 ton, using two floor jacks together (preferably matching twins) doubles the lifting capacity, while evenly distributing the lifting action.
The lighter tonnage jacks are cheaper to acquire than heavier rated jacks, which often are not make to reach as far in nor lift as high.
I'll look into that cross beam setup for the floor jack, looks very handy, thanks!
