I don't buy it. All engine builders I know recommend getting some temp in the motor before putting it under load.

I agree it would not be a good idea to have RV attached sitting 100 feet from onramp start engine and take off. BUT starting and rolling right after start driving thru the campground and streets leading up to where you have to accelerate will not hurt a darn thing.
