Have a look at these mate, McHitch.com.au uniglide trailer couplings. located at Lithgow. Also with those "El cheapo" winches they will burn out, trying to pull heavy objects uphill over a distance. If you go a winch, either a Warn or a Thomas winch is the go. Both 12 volts,use a h/d battery on a three stage battery charger. Hope this helps. cheers Ron.
