The ride is probably alot better with the truck Camper setup as compared with a towed trailer.
Thats would not be my cup of tea riding in the towed trailers. Wife tried that once and scared the H@@@ out of her...
I think different states have different laws about this... I remember reading about one state that required a live intercom to make it legal.
My sister had plans to carry their big dog in the fifth wheel on trips. They stopped after 50 miles on the maiden trip and their dog was really in bad shape. To this day they can't drag that dog inside their 5th wheel...
Not for me
