This is a Used 2025 Wingamm Oasi 540.1 built on the 2023 Ram promaster chassis. 

This is one of the first ever Wingamm USA models. This was a customers who has since sold it back to the dealership and purchased a larger model for himself. This vehicle sleeps 3,  has seatbelts for 4, and has a large enough dinette seating array for 6. 

This vehicle is 17'10" long and is just under 10' tall. 

It has 3,695 miles on the odometer. Which means it is still well under the warranty limit for the Ram Promaster chassis.
