Thanks for the reply. I'm currently trying the mod first. I also heard that different type of landing gears behave slightly different on eve surface
However, I'm 100% certain that the advanced tweaks thing doesn't work. I already tried adjusting spring/damper strength, it only made the problem worse. Before the adjustment, only the wheels sank into the ground. After disabling spring/damper, the entire landing gear sank. Try retracting the gears sometimes helps, other times as soon as the gear button is pressed, the entire spacecraft explodes or go faster than light in a split second.
Also, my spacecraft is super heavy, it weighs nearly 1500 ton fully fueled on kerbin. Allows the craft to rest on eve surface with landing gear retracted is quite risky.For example, when I try to lower the landing gear with a fully fuelled craft resting on eve surface, the gears simply shears off completely, and I'm unable to take off.
I'll try messing around and let you guys know the results after I'm done.
