from September 2019 was the first time I heard of L'air. They are a very new company and only showed their first pre-production trailer last year
at the Elkhart RV show.
The company was discussed a little bit in a Facebook group and the going theory is that they were the original shell suppliers for Hymer NA's short-lived Touring GT. When Hymer NA went under, they could have pulled in some of the former employees to become a full-fledged RV builder.
Their website has the following note: "Due to COVID-19, the Signature Camper Program is on hold until Spring of 2021
The Signature Camper is their Hymer Touring GT do-over, and was shown on their website well before the Heritage, so I would not be surprised if the Heritage is in the same boat. If there are any
models floating around out there, there are very few.
One more thing I noted was that when searching their phone number, it came up as the number for a pool manufacturer at the same address. So they may be prioritizing their core business right now rather than chancing it on a brand new product.
