Mystery RV Part

It's the thingy that held the "don't step off the plastic runner" sign when your rig was at the RV show- right before you bought it, of course.

Portable table stand so you can set up a table anywhere.

I agree with the previous post, a portable table stand.

It is a lunar landing module stand. Keep "just in case".

It's the base for some kind of chair or table.

Cool - that makes sense. I would have also accepted - antenna for communication with alien worlds and UN black helicopters.

Thanks again.

I used google image search for the first time and found this:

I believe it is a portable table stand to use your table somewhere besides in the RV, but it will only work if your table has a single round post, about 2 inches in diameter, support in the center of the table. If your table has 2 posts you would need another stand. It would not work with my table because it fits into a rail on the wall on one end and has a single square leg on the other end.

It' a RV CHRISTMAS tree stand.

I saw this on a Klingon Warbird. It's a Techieon Beam emitter.
Totally useless unless you posess the reactor, so might as well use it as a table stand.
