I haven't seen the dual door option.
With the small kids you may want to purchase the OEM half doors but beware they are expensive. Sometimes you can find them on ebay.
I am purchasing the tubular doors from 4 Wheel Parts. I like the Rancho Tubes but they have several other brands to choose from. Since you have small kids these may not work for you but wanted you to at least see them.
Here are the Ranchos
They are on sale through today.
