2. You might want to not have just a regular high-tonnage hydraulic jack along - the better high-tonnage jack is one that extends higher just in case. i.e. A jack with dual cylinder capability so as to extend more than normal. i.e. What if the road shoulder is slanted downwards from the roadway, and the flat is on the side away from the roadway and you have/want to get the RV axle with the flat somewhat level?!
Also note when you are buying a hydraulic jack that it needs to get under the axle/frame when the tire is flat or completely gone. Clearance can get very tight. Many higher tonnage jacks with decent lift may not go low enough.
My high lift jack also starts out very low, then extends to around 20 inches. Just in case, I carry a full size shovel so that I can dig a shallow hole for the jack base if the jack doesn't start out low enough. Sometimes the hole might need a board in the bottom of it to make a firm base for the jack, in which case the hole would need to be large and deep enough to also make room for the board. My jack has a long handle so I can work it when it may be hard to otherwise reach it under the axle and in the hole.
