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.
