Purchase advice MERCEDES G WOLF

Hello, I am interested in a Mercedes G Wolf. Can you give me some information about the different engines? But the 72hp engine is too small for me, I want to get wood in the forest and do forest work in general, but also drive normally on the road. How many locks does the wolf have and which ones? How is it with the switch-on all-wheel? Can I use this also on normal road, like with the VW Iltis? Can I switch it on while driving? Can I use this en G-cars also pull heavy trailers, because of the gearbox? How much is the official trailer load? Would not really be happy about some answers!! Best regards Jochen Sturm
