It's always seemed to me that the deltaV needed to capture and circularize will be similar to the deltaV needed to transfer to the orbital intercept... ignoring inclination. So if it takes you 6k to get there it will probably take you (very roughly) another 6k to capture and establish a low circular orbit. And then there's the landing. The gravity feels like 2 to 3 times that of the Mun. And based on Ziggy Kerman's vertical leap that seems about right. My landing spot is too hilly. I need to find a better area to land.
