It's not THAT hard to get a camper somewhat level, unless you are parked on the side of a cliff and falling over! Find your spot you want to stay for the night, position the tires, see how much off level you are. Then move the rig forward or backward about 5 feet and place leveling boards, or Lynx blocks or, whatever you may have, and pull the trailer back on the boards, or block, or whatever. A "perfect" level is not necessary,but there's no reason why you can get it close. You may not have to unhitch if you are somewhat level front to back. But if it is way off, especially if the nose is low, simply unhitch and raise the tongue. You don't even need to move the the tow vehicle. In the morning when you get ready to leave, re-hitching takes only a minute.
If nose needs to go down, just move to tow vehicle forward a foot after unhitching.
Still, there's really no reason why you can't get relatively level, even hitched, for an over night. Yes, it IS worth the little extra effort to get the boards or blocks out and take that 5 minutes to level. It makes the inside of the camper so much more enjoyable.
Once level, slides work as they are suppose to, no danger of damage. Refrigerator works like it suppose to to max efficiency. Air Conditioner works correct with no threat of stressing it. Even the microwave oven turn table will work better if level! Take the time and throw something under the tires of the trailer, and then you'll never have any issues with anything.
While you are at it, drop the jacks on the back of the camper so it helps eliminate some of the wobbly shake too.
