table mounting question

I'm in the beginning stages of some alterations to the interior of my tow behind toy hauler. The front area was a U-shaped dinette/sitting area of sorts. I'm changing that to a permanent bed and a smaller sitting area. I need a table. My current plan is to have a 24"x24" table that will be supported by a typical removable pedestal leg system. I'll want to get the table out of the way at night to provide easier access to the bed.

Here are my questions:

1. Will a single pedestal leg provide enough support for the 24x24 table top? (The top will be used for regular purposes, eating, laptop, writing, nothing abnormally heavy.

2. Are there any drawbacks to the recessed floor mounts, other than dirt getting into them?

3. Do the legs come out pretty easily or can they stick and be a pain to remove and re-install daily?

4. Do the legs have slots and tabs so they stay in one position? I read where someone was complaining about their table spinning.

Thanks.
