Happijacs, what will happen if.........
When reading about the operation of my happijac electric camper jacks, it stated numerous places, "Never raise the back of the camper higher than the front". Why? Is the location of the front jacks...

I look at it as weight transfer, front jacks already carry a lot more than rear. As the rear jacks are raised some of their weight/load moves to front. IE not paying attention I can easily raise one rear jack off the ground-
To a degree yes the fronts are at fulcrum point and the higher rear is the closer they get. Also they are mounted to camper at 90°, feet, front & rear are fixed to ground so as you raise as mentioned and load becomes less vertical thru legs (tube) is when tube failure more likely. Even with front jacks fully collapsed and rears full extended I doubt you could topple over on its nose, though mostly because either the jacks would buckle or mounts fail first.
Be interesting on camper destined for recycle to test some of these failure scenarios to see what really happens.
But not on mine, going up/down nose is always higher till it contacts bed of truck.
