That is our plan though we haven't been out in the Phoenix since we purchased the table. The ladies from Vermont said they used it inside (and I'm pretty sure outside too).
We intend to use it inside and outside when needed. So far we have not needed the outside table that we've been carrying, well, maybe once. The few times we didn't have a picnic table, we just winged it and lounged around in our chairs using other items as side tables for food. That said, we've only set up the Phoenix table two or three times since we purchased in May of 2013 - and that's while we were on board full time and working for a year and a half. One of the times we set it up was simply to demonstrate to people planning to buy a Phoenix.
We do have a custom, flip up "desk" that we used for our computers when we were working half time on board and needed to work inside. Even that is seldom used now that we've retired. I'm pretty sure we never put it up just for eating. We ate sitting in living room chairs at the old house and that's primarily how we eat when on the road... that or at the picnic table. I guess it's kind of funny that we do the "sit down" meals more when we are out in the woods than when we are inside a house.
