Which RV you are talking about.
In my case, when I was looking into bringing my -10 home, there was no way it would fit into a rental trailer. Gear is over 8' wide, and tail is over 8' tall.
In a semi, maybe, but not into anything I could pull with my pickup.
I ended up using a flat bed implement trailer from Hertz. See this thread for a photo.

Start off your search with the specific dimensions needed, and dont be too surprised if you cant find what you need.
Partain is pretty good, but he is limited in size capability----------I would have had to remove the engine, and gear, to make a -10 fit in his trailer.
Good luck.
