Process for leveling with the hydraulic jacks?

Hey Yall,


Whats the correct process for leveling? Id like to keep from torquing the body too much so the door will close properly.


thanks,
Aaron

One important thing to remember is to not come close to lifting
even one of the dual rear wheels off the ground. Your AS will roll
and you will likely bent the leveler mounting brackets. Yes,
using wheel chocks will help but may not help enough.

When the leveler touches the ground/pad, turn the crank maybe 1/16 to 1/8 more...and that's it.

They are just to keep the body from rocking, you should not see any lift on the body or panel.....if you do, your turning it way to much.

Is the 345 system designed for leveling or just stabilization?

Best option might be block up the wheels for height and just use them to stop the wobble.

Leveling side to side is done by placing blocks of wood or other sturdy material under the two low side wheels. This is usually done with the tow vehicle is still connected and the trailer is backed onto the blocks. Once it's level side to side, place wheel chocks in front of the wheels so they can't roll and disconnect the trailer from the tow vehicle. Front to back leveling is done by raising or lowering the tongue jack as necessary. When the rig is level side to side and front to back lower the stabilizers to keep it steady when you walk around inside the trailer. I've never had a problem with the not door opening but if you do, raise the stabilizers and lower them again with a little less pressure than before. Pretty simple once you've done it a few times. Just remember the wheel chocks - you don't want the trailer to roll when you disconnect from the tow vehicle.


Sorry, I didn't notice hydraulic jacks in the topic header, but I'd still do it as described above. Users report problems in some circumstances with them.

On our 350 each jack is rated for 9000 lbs. We have the auto level system, but I prefer to do it manually. I do what ever end is low, bring it up to about level, this HWH system does the jacks in pairs. Then bring the other end up to stabilize. If you need side to side adjustments do it next.
It is best to start with the coach close to level before deploying the jacks.
It will become easier after you have done it a few times.
And always use wheel chocks, especially on unlevel ground. These jacks will not keep the coach from rolling like air345fly said.

My system does each jack independently. Sounds like I should be picking a pair to activate in parallel, deploying each of those until ground contact is made, and then lowering until level. Then move on to another pair.


However, if chocks are not going to hold everything in place then the system is not very useful and I should just buy wheel blocks to drive up onto.


I thought I had seen videos of hydraulic jacks lifting rigs off the ground. Perhaps that is newer models and the system has been perfected?

I use my IPhone and Level Mate Pro to level my trailer. Before that, used the Measure App on iPhone - it has a very nice two-circle bubble feature to measure side to side and front to back level.

On Large diesel motorhomes the jacks are fixed in place and just
come down. On our Airstreams the jacks pivot from their horizontal
parking position to the vertical position and then start lifting.
It is this pivot that can be a problem. The pivot is not strong enough
to stop the motorhome from rolling.

I have the same model as you. 1 year younger. I noticed that you can only level the rig by one or the other side, OR the front of the rig. You cannot lift the back wheels up too much because the E-brake engaged and rear wheel contact is what keeps the rig from rolling off the jacks. it is a bit of finesse to do enough leveling but not too much.
