The only tinkering needed is to adjust the jack height so that the broken jack does not carry any weight. I can do that easily using the bubble levels I added. It does not matter that the COG is forward of center. The good front jack can be extended to keep the front higher than the rear. All I can tell you in addition is that you can try this for yourself. It is real easy to do and you can easily take the pressure off of any one jack by adjusting the others.
The COG is all that matters. It’s basic physics (statics) that when an object’s COG is outside of its contact points with the ground it will tip over. It’s really that simple.
So if you take a camper where the COG is forward of center, you cannot form a triangle with both rear jacks and only one front that includes the COG inside the triangle.
If I tinker with the jacks and raise a rear one, it lifts off the floor. If I raise a front one, the opposite rear one lifts off the floor. Being careful and deliberate doesn’t change the physics. The diagonal becomes the teeter totter support and the chunky kid is always sitting on the front. A front jack cannot be made to not carry any weight.
