Hydraulic Levelers

Not bubble levels but usually an electrolytic tilt sensor. Dual axis (5 pin) sensors are accurate and inexpensive. Once you tell it what level is, it should return to that state each time you tell it to "Auto Level"

On ours, the automatic feature finds level for you. It is not set in one position by length of the jacks, it is set in the coach level position, regardless of how long each jack extends. It is often easier to use than manual but on some sites, manual seems to work better. We have Power Gear Jacks.

When the auto feature is having problems finding level on a particularly lumpy site, we can often solve the problem by putting wooden blocks under the jacks on the lowest side (either front, back, left, or right).

You should level the system to your liking... I prefer slight nose up and slight right side up...makes water run off the back and also takes into account my heavy slide when out. Once done, follow the directions for the zero point...basically telling the system that is now the position for level.

I will say this, auto level is not always the most efficient. I have pushed the button and walked away, only to find it level with tires off the ground. I can go back and manually do it, and it is level at a much shorter stroke of the actuators.

Mine has a sensor and will auto level anywhere.
I can also manually adjust. Mine in HWH system.

brand would be helpful but i think they are all about the same.

On our HR Class A, I stopped using the 'auto' feature and simply deployed them manually until I felt the coach was level. I don't use a level, instead I use a bedroom pocket door and the exit door; when both will hold position without further opening or closing, the coach is level. Many rv'ers use the fridge door as a level guide.

We have the Big Foot system and just push the auto button and walk away to do the rest of the set up. Perfectly level each time which is important with the full wall slide.

I have the semi-automatic HWH Levelers on my 'C'. Because my RV is pretty close to the ground, I bought the kick down type. All four go from horizontal to vertical at once. Then a screen that I can see from the driver's seat lights up a button for either front, rear, left or right pair. I push the button that's lit until the light goes out. Then it usually lights up a different light and I repeat the process. When all the lights are out, I'm level. Expensive, but they sure are handy when its raining or cold outside.
