The sort of off-road activity you choose depends on whether you are interested in rock or hill climbing, mud bogging, trail riding, sand dunes, etc.
My first recommendation is to prioritise front-end protection and recovery for a P38, since the lower radiator is exposed. Therefore, investing in a front bumper, skid plate, and winch combination is crucial.
Lighting, lift (if riding on coils), and side sliders. Ability to inflate tyres and differential locks are more important to me than a rear bumper.
Some individuals heavily modify their automobiles with accessories that are seldom used, neglecting essential modifications.
Understand the appropriate times and methods for using your modifications, when to activate lockers, the degree of approach/departure angle you have established, how to use your winch, and how to utilise snatch blocks. Numerous factors.
