I carry multiple jacks between my car and my class A ranging from a 2 ton Floor Jack to a 12 ton Air/hydraulic jack-jack.
I will tell you of the issues
FLor jack goes under things the bottle jacks won't fit under.. But alas even it is a bit high for the car.. So I have to find an alternative point and jack it up a bit (unload springs some) then put a block (Big 4x4 thing I carry) than re-position then I can lift the axle to change the flat, and then let it down, first removing the block, the full tire gives enough clearance
on the RV it depends on what I'm doing, some things I have to use much the same procedure but with teh 12 ton jack, other things I can just use the 12 ton.
I like that jack-jack (The air operated pump is like a jack hammer) picks stuff up real easy.
