We had a similar choice as well. Just the two of us and we decided on the 2720SL. What with the abundance of rain in CA this year we have yet to get out in our new TM, though every time we open it the neighbors come by for a tour. Here are some of our assumptions leading to our decision.
An important consideration is your tow vehicle capacity -- We have a Honda Pilot and I determined that the 3023 would be too much trailer for it to handle.
We liked the flexibility of the open space the SL offers - maybe in the 3023 as well?
We assume that in CA we will most likely be outside more than inside.
We assume we can set up folding chairs in the lounge area when others may want to be inside with us.
We really liked the idea of the two smaller side tables for the occasions that we have to eat inside.
We consider putting a small plastic 3-drawer unit next to the fridge, but have yet to use the TM to know for sure.
Good Luck with the decision,
