Copy the CamperInterior.xml file to folder : \Grand Theft Auto V\menyooStuff\Vehicle
To load the file : Open Menyoo, select Vehicle Options, select Vehicle Spawner, select Saved Vehicles, select Camper_Interior.xml

Oh, if you see anything you wanna remove, such as the chairs or the gun above the door, just delete it :)

I create a drama series for Youtube and this camper will be featured in episode 62 and later.

Changes V1.1
Saved the file as a vehicle, instead of a spooner file.
