The Fuso youtubers are obviously living in a different world. We know SBunny will be more reasonable in price. When I was at Quartzsite last Feb, I went to a 'renowned' restaurant and some people had a huge semi type diesel with what looked like living quarters, so I asked and they said "That's where we keep our toys". Looked something like this without the trailer on back. They probably had an 80' long 5th wheel back at the park.
