"People immediately stopped and were very good in helping us. It all happened in very slow motion and I suspect it was just that one gust - wrong place, wrong time."
Friends of the couple were planning to travel to the same holiday destination today, Mr Joblin said, and he regretted his decision to set out yesterday.
"I knew there was bad weather forecast but thought we'd get through before it came. I'm farming [at] Bideford and it gets windy out there too. I should have known better."
Mr Joblin said he and his wife would reconsider their holiday plans and "regroup - we'll have to work something else out I guess".
"We'll have to figure out what we can do and what we can't."
High winds pummelled firefighters, police and friends of the couple who had helped remove belongings from the caravan and ute after the crash, and traffic was halted briefly while paramedics checked the couple for injuries and the caravan, ute and debris were cleared from the road.
Eketahuna Police Constable Donna Olliver said high winds can plague drivers and motorcyclists and endanger high-side trucks and towed caravans on the stretch of road from Masterton to Mt Bruce and Eketahuna. Vehicles flipped "like turtles" on the stretch of road were not uncommon, she said.
She said drivers must heed weather warnings and should "park and wait for improvement" when road conditions become threatening or dangerous.
