In terms of Aerodynamics RV trailers present the biggest challenge. Overcoming the wind is a very big challenge. RV trailers can be heavy and large with more frontal area than any other type trailer.
Most other types are not as tall and wide as an RV trailer.
Nevertheless if you follow the ratings including frontal area info found in the OEM's fine print you will be fine.
In the end most mismatch problems stem from owners not using or understanding the towing parameters.
How many actually weigh their rigs in order to understand how balanced their combo is?
It is easy to blame the salesman however, since the coming of the internet info on towing parameters etc. is readily available. The end user has no one to blame but themselves if their combo is mismatched.
Common sense and experience goes a long way towards making a sound decision.
