Level on power jack

[mjones12]

I just got a Barker power jack that has the level on top, and I'm not exactly sure how to use it. The level is sort of loose in its housing with screws around the outside. I'm wondering if I should get my trailer as close to level as possible using a traditional level, and then center-up the Barker level and tighten the screws, thus calibrating it. If that's not the best way to use it, I know some of you guys and gals can educate me. I couldn't find anything in the owner's manual about it. Thanks.

Those small levels are for a reference. Trying to level an RV with a 1 or 2 inch level is like trying to level a house with a 6" level. I use the outside level as a reference then I throw a 4 foot level on the rv floor to get it dead on level. Then again I am an engineer, and I tend to get carried away with stuff. (just ask my wife!)

Thanks. I agree with your concept but just can't justify traveling with a four-foot level for a 20-foot trailer.
Does anyone have a jack like mine with the circular level on top, who could tell me how you use it, if at all? Thanks. I am very curious about what appears to be the adjustability of it, as described in the original post.

I keep an 18" level in the trailer, and check the kitchen counter and/or floor with it. Works fine for me.

yeah a smaller one works. does not have to be perfect but you want it close

I would level your trailer with a normal-size carpenters level, fore and aft and side to side, by placing the level on the trailer floor. Then check the bubble level mounted in the jack. If the bubble is inside the circle, tighten it down - otherwise adjust it if possible and tighten it down. From then on it will indicated your trailers "levelness" close enough !! (Close enough for me at least, but then again, I'm not that anal about that type of thing !!! LOL)

Thanks. That's what I needed to know. I knew that level on the jack was loose for some reason, so I'll center it and tighten it down when I get the trailer as level as possible. Thanks for confirming that I was on the right track. I agree with you that "real close" to level is usually good enough.
