Really easy to do - simple case of bolting it to vehicle.
The electrics plug into the RHS of the vehicle - just remove a rubber bung.
I was lucky - mine came fitted with a towbar. I just had to renew the electrics as they had bad water ingress. I also fitted caravan supplementary electrics at the same time.
Not planning on buying / towing a caravan, but useful for powering camping accessories.

Steve.
