No it's not. The kind of mud that sticks to everything, three paces and you add 300mm to your height, kind of mud. Water-logged carpet stinking in humid steamy Equatorial rainforest after 4 days ...
I like my rubber mats and moreso - the no nonsense, no FOOTWELLS. Just a hose out flat floor (or park it in a river 600-700mm deep and open the doors for current to flow through)
Apart from above mentioned ablutions mine gets a wash when sent in for a service (if I forget to tell them NOT to), and after the drive out of the jungle it gets an underbody hosing to liberate several dozen kilograms of caked mud from under chassis (not really a "wash") before the few to several hours highway run home.
(I don't have a beard and MUST bathe personally every day - if I want my wife's hugs)
