The 516-mile (830km) North Cost 500 has seen a boom in popularity in recent years following the pandemic as families turn to “staycations”.
The official website for the route, external – which circles the Scottish Highland coastline from Inverness Castle – warns drivers of the “challenging” conditions on single track country roads.
Mr Schmidt said the accident has made him think how he can better prepare customers the route.
He said: “People need to be aware, especially if they’re not an experienced motorhome driver.
“The NC500 is tricky, from the roads to the weather conditions and generally most drivers there are tourists.
“It’s not the same weather as in England, it’s completely different.
“I think we need to be a bit more mindful of telling them this is not going to be easy.”
Storm Kathleen brought disruption to travel across Scotland last weekend, with winds of up to 90mph recorded in places.
