Why?

If you seriously have to ask this question then you do not need to be owning a truck camper...

Hmmmm...your response clearly indicates that you do not know the answer to my question either, and camouflage your ignorance with such a useless response!

"If" you are truely so wise and "all" knowing why are you here if all you're going to do is insult those of us that are trying to learn?

Your response added absolutely NOTHING to the advancement of truck camping!

PLEASE DON'T BE NASTY TO A PERSON WHO IS TRYING TO UNDERSTAND THE REASONING BEHIND THE STATEMENT!

I disagree with this statement.

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.

There really isn’t any reason to when you are loading/unloading. Instead, I think the common recommendation is to raise the front slightly to be able to pull out without dragging. Off the bed, you probably would only need to barely have the front or rear out of level assuming you picked a reasonable spot.

"Never raise the back of the camper higher than the front"....Why”??


“Stop, the stove is HOT, DON’T TOUCH A HOT STOVE”!!

The center of gravity is roughly 1/3 of the way back on the camper floor on most campers. It will not topple.
But the jacks are not designed to take a lot of side (right/left/fwd/aft) loads. As far as I see it, you would create a forward momentum on the front jacks which would try to bend them backwards. They are under a lot of stress as is and don't have a lot of reserves. A jack mount might fail or a jack leg might bend, or a jack might loose footing and slide away. In which case you will end up with a buckled jack and a camper on the front or side...
