What to do with dining table

I am in the process of putting in new flooring and replacing the booth dinette with a table and chairs in our motorhome. What I don't know is whether or not it's necessary to fasten down table(and/or chairs) while traveling. If the answer is yes, to what do you fasten? I really do not want to permanently fasten the table to the floor. I need some feedback from those that have been there and done that, or those that currently have the same configuration. I'm also thinking that four legs on the table are better than one pedestal in the middle.
