I like chilling with a tri-wheeled rover.
I tried to build a tri-wheel, do you have a picture I could work off of?

This is what I currently am working with for a... maybe 20km trek? Also this is obviously not the aforementioned tri-wheel attempt, lol.
Edit2: Ok, so those side wheels aren't that necessary to stabilization, so I removed 'em and now I can easily slot it through the lander's legs.
