landing is not a problem....taking off might be.
-acceleration is bad. A normal takeoff technique must be used because soft field technique in a twin puts the plane in the air before Vmca.
more time of nosewheel on the ground because of that.
more stress on the mainwheels because they hold the weight of engines while encountering bumps, jolts, all that.
partial power on brakes is discouraged (debris can hit the prop)
and besides...twins are normally heavier than singles...they use more runway, they sink deeper into the grass, etc etc etc.
itīs not impossible..itīs just not the best situation for a piston twin, even tho most are perfectly capable of doing it.
Just an opinion.
