This discussion on hitch height is interesting and enlightening. I have two thoughts about it. I have always tried to get the motorhome and car heights as close as I can, but if there is some variance I have thought that it might be better to have the car higher. My reasoning for this is that if I slam on the brakes, the back of the motorhome should come up a little, minimizing the height difference. Secondly though, if the manufacturers (both Roadmaster and BLue Ox) say +/- 3", either should work okay.
Having said that, your ideas as to why the motorhome should be higher, make sense too.
