Hello!
Here is a game ready Eaglewind RV I created for Motion Logic Studios. This was designed to look very similar to a Travelaire, with some minor adjustments. The RV was intended to stay at a lower tri count while maintaining a majority of the details with it coming in at 34k tris with 3 textures.
This is currently for sale at https://assetstore.unity.com/packages/3d/vehicles/camper-rv-trailer-158123 It comes with another RV and the images on the store are rendered in Unity.
