Campgrounds, glamping sites, recreational vehicles and anything else that offered fresh air, physical distance and a decreased chance of cancellation due to Covid-19 regulations saw significant boosts in bookings in 2020.

Internally, companies offering those products believed it would be hard to keep up the rapid growth into 2021, but the sector's upward trend has continued, and more amenity-rich camping products are coming to market to meet demand.

"In 2020, as people switched to domestic and drive-to travel, it was great for us," said RVShare CEO Jon Gray. "We wondered how we would top that growth, and we have. We've continued to see business accelerate and have had strong growth this year on the back of what was dynamic growth in 2020."

A recent survey conducted by Wakefield Research for RVShare found 45% of travelers included RVs in their top three types of accommodations, a 13% increase from 2020. It also found that, when planning a 2022 vacation, half of travelers are considering outdoor activities.
