Bottle jacks....Screw jacks...Steel Shores????

Just a thought sue, but isnt that screw jack gonna take quite a bit of leverage to lift a camper. It seems like it would be great to set something on, but a biotch to lift something. I know that construction scaffolding often uses bases like those screw jacks to adjust the scaffolding. If there is any weight on it, you cant lift it to save your life.

I would personally steer away from those. Bottle jacks are far stronger due to the assistance of hydaulics.
If it were me I would use a bottle jack to get it level, then use wood or really sturdy jack stands to hold it (much more sturdy than the one you have pictured). Plus then you would only need to store one bottle jack and 4 jack stands.
Or whats wrong with the old, drive one tire up on a 2x6 theory? I assume your trailer has a jack in the front to get it on and off the hitch, between driving up on a block and the jack on the nose, I would think it would be cake?

Bingo!!!

A triangle is the most stable arrangement anyways.

When you get to your campsite & disconnect the trailer, keep the nose down slightly. Place your jackstands or blocks at each corner of the rear & jack up the tongue until level. If there is any side to side leveling needed, you should be able to eyeball that as you are placing your jackstands under the rear.

If the tongue jack is a PITA for you, there are 'lectric ones available.

The site lists a turning bar in 12", 24" and 36" which was needed for lifting on the MINI Screw jack......
BUT...under the "Steel Shores" model sold WITH the "needle / roller bearings", it emphasizes how "the bearings allow for significantly less friction and easier turning under load".
It doesn't mention a turning bar....so I assumed the wingnut with the bearings could be turned without it.
I may have assumed wrong...
I can call the company and ask.

STEEL SHORES WITH ROLLER BEARINGS
In the product animation to the left, you will notice the needle bearings inside the wingnut.
These bearings greatly reduce the amount of friction when the handle is turned to adjust the height under load.

We just don't like the stacking block/ramp routine. Tried it a few times with our teardrop trailer and didn't like it for some reason. We may revisit it as we haven't tried it with the bigger camper.

We've been planning to pick up a set of 4 of the stacking ones like Tom mentioned.
We have these jack stands:
Torin T43006 3 Ton SUV Jack Stands, plus two 2-ton jack stands.
We'd use the jack stands for support, not the bottle jack.

Yeah Jack, we have the traditional A-shape trailer frame, and use the front trailer jack wheel to raise or lower, then the jack stands, to support.

ya know how sometimes when you write out or describe your problem to somebody else..... the obvious answer just suddenly becomes clear?.....I think that may have just happened....

The cranking rod on the scissor jack is a major PITA...we just wanted to dump the scissor jacks....but really the issue is the folding cranking rod....so we looked and see there's a few different rods available and look like they'll stay on much better....think we'll try that first.
Thanks all ya'll!

Glad we could help

seems like the majority of trailer owners use that method, so its most likely the most effective
