It will be more though but any of this is small compared to potential aero drag of what you put on the trailer, or the huge hit you get crawling around off road even without a trailer.
RR doesn’t mean much with trailers. It’s the aero penalty. Unlike a car with work commute and shopping, an RV spends little engine time off highway. Generally.

The tracking stability of Tandem means fewer steering corrections. Etc. It’s just easiercin every situation. ESPECIALLY backing.
