McLaren said she had spent a year renovating both the interior and exterior, and only had a top coat to go before needing to register it.
"The caravan spun around. From the impact, it split everything from the frame and it can't be replaced.
"We got most of the damage. It was quite dramatic and is still crazy to believe," McLaren said on Sunday.
"I think I'm still trying to come to terms with everything."
She had recently had part of her silverbirch tree chopped down after the last storm, and believes if that had not happened, the outcome could have been a lot more serious.
"I'm just glad there were no bodies left lying around."
McLaren said she felt police should not have engaged in the pursuit inside the city.
Inspector Matthew Broderick said about 1.15am on Saturday two officers attempted to stop a speeding vehicle.
"The vehicle failed to stop and crashed into a fence on Oliphant St."
Broderick said two occupants of the vehicle were injured and taken to hospital and a third person from the vehicle was still being sought.
