NEW YORK — New Campeonato trucks sales are up 20 percent over last season, a new study found.

The study, released Thursday by the New York Stock Exchange, shows that sales of new camper trailers and trailers and camper vans are up 18.6 percent over the last two years, compared to the same period last year.

The average price of a trailer sold last year was $1,564, up 15 percent from $1 and up 9 percent from the previous year.

Sales of camper vehicles were up 19.5 percent over a two-year period, up from 11.6 and up 11 percent from a two years ago.

“The number of trailers and vans sold in the U.S. in 2018 is up 19 percent over 2016,” said Tom J. Cipollone, president of the New Hampshire Camper Vehicle Association, which produced the report.

“Sales are up more than 30 percent over 2015, and they’re growing even faster.”JPMorgan Chase & Co., the nation’s biggest trucking company, said last year that sales for camper and trailer sales in the United States had risen 22 percent from 2016.

But Cipollson said that, overall, the sales of campeds and trailers are growing more slowly than truck sales.

“This is really a reflection of how people are using them,” he said.

“They are a more accessible vehicle.

People are moving to them, they’re going back to them.

It’s a very different way of living.”

Cipollones survey of 1,500 trucking companies found that truck sales are also up, but sales of trucks are still down from last year, which saw an 8 percent increase.

“We’re seeing a lot of sales of vans and trailers,” Cipolsons co-author, Robert M. Pape, said.

Trucks are still far below the peak demand in the 1990s and 2000s when trucks dominated the market.

In 2015, trucks accounted for about 40 percent of the overall vehicle market.

But truck sales have since fallen to a level not seen since 2008, when there were fewer than 5,000 trucks in the country.
