How much driving on the land have you done ?????
I haven’t done much but I’ve been on permission a few time around Northumberland, and permission down your way and father down to Notts , and off permission up Scotland in the dead of winter and never got stuck.
Youve obviously not been out with a proper off roader , some of whom have land anchors, winches, ground ladders, hi-lift jacks. Those lads never get stuck.
Go out six at night, drive miles , get back 7/8 in the morning.
You talk like an expert , but sound like a novice; “you can’t get on land winter be stuck straight away
