We are planning to use the Siena as a camping vehicle. No need to sit 7 or 8 passengers. Only needs to seat just the 2 of us. The non-removeable 2nd row seats was the deal killer for the 2021. So was no point in waiting for it. Purchased a new 2020 instead. On the 64 mile trip from the dealer to home, 33.7 MPG for the 2020 XLE. Not a very big sample but was pleasantly surprised it was that good.
