Yeah, the bottle jack is going to have to lift more than what a "corner weight" would be. Although a six-ton can lift nearly the whole weight of a 24' Class C, the force it takes on the handle would be more than we can generate laying down, reaching in, etc. With the sway bar brackets and the attachment for the track bar, I'm running out of jack points on the axle!
You can take the front calipers off with a wrench, unless the slide bolts happen to have TORX heads. My slide pins weren't damaged, but I used the new ones that came with the new pads because thay had ordinary hex heads, albeit metric.
You can replace Pads, Calipers, Hoses easily, but if you want to pack both the Outer and the INNER wheel bearings, the Caliper Mounting Brackets have to come off. They're a large metric Cap Screw and I think the head size is 21MM. Which I didn't have so I had to go buy one and it took a breaker bar to get them loose. The torque spec for them is pretty high. I can check socket size and torqe spec if you need.
