I would suggest that you join a club where you have a mixture of experience in driving and recovery. This will help you learn the ropes as it were for recovery without buying your own recovery gear and winch for example, and you will get advice from experienced off roaders about tyre pressures which may mean you won't need to be recovered. i agree get ratyed recovery points and a compresser as minimum. UHF is also necessary for off raod , but once again a club or club member may be able to "lend" a newby one for a few trips.
