The technical requirements and know how and the inherent frugality of using a car to tow all have some appeal to me. I might change my mind on a long climb though.
This Eriba manual is well done:

When parked, do not allow the engine of the towing vehicle to run more than necessary. When running idle, a cold engine releases more contaminants than usual. The running temperature of the engine is achieved more quickly whilst the vehicle is in motion.

was interesting to note.
I think speed and loading come into play more than with the units we have here.

The caravans are designed by HYMER AG for a technically permissible maximum speed of 100 km/h (60 mph). Therefore never drive faster than 100 km/h (60 mph).

Many countries in Europe have a 50mph limit in place when towing on motorways so you wouldn't do 60mph anyway.
That manual contains lots of good information. It's very thorough and well written. I'm very impressed.
