I am not sure, as we were travelling in a tour bus.
I can't say I saw any trailers in the car park but I'm assuming you can park in there. I'd give them a ring to check. But I thought it was fairly secure but not locked or closed at night. Its better parking there than on a street anyway, there's really no where else to park because motel is in Main Street.
You drive off the main road to the reception block then into the carpark and the buildings are at the end of that. We stayed a couple of nights and never had any trouble.
There is a court yard on the right as you enter the premises, that is fenced and has several units facing onto it. It is fenced and prevents direct access from the street , but could be accessed by walking about 100 m into the complex.
We had a camper trailer , and car too. Both had gear that could be tampered with tyres , fuel and recovery gear . We stayed in the units right in the court yard , and felt quite ok.
The court card is not huge ,and can be tricky getting in/ out.So if the trailer is long beware. We had a Big Foot hire camper if you want to check on web.
As a tip we reget we didn't get to stay a day or so , rather than an over night stay. There is fair bit to do and to discover the unique history of the town . We stayed over night after spending 6 nights in the Great Victoria Desert , crossing the Anne Beadell Highway. So was a welcome respite . Unit very clean and presentable , but older .
We had long bike cable locks on the tyres and fuel , light weight and cheap. Had to have them travelling through communities along the way ( Kalgoorie , Laverton, Marla , Uluru, Giles , Warburton ) . Never felt unsafe , very welcoming country people . We had 10 and 13 year olds with us .
Beware on the wine if restocking , one bottle per day , and you have to register your drivers licence to enforce . No drivers licence , no wine . You are allowed a carton of beer , 24 cans per day . So if you want more , take the wife with you !
As above there is plenty of parking on the hotels grounds but it is fully open to the public so can not be totally secure but we found the hotel friendly and helpful so if it's really valuable I am sure in a place like Coober Pedy they would be able to put you in touch with a secure facility. Do not let this put you off the whole Coober Pedy experience is worth it and the place has loads of character both town and people.
Hope this helps and ask for bottle of wine not glass (it must go off very quick). Have a great time!
