The Acura MDX absolutley can't be towed 4 down (and this is specifically what the manual refers to when saying can't be towed behind a motorhome). Preferred 'emergency towing' guidelines are for all 4 off the ground or for the FWD verson, Front wheels off the ground . I have an AWD MDX and just purchased a FWD Accord. I specifically got the FWD Accord so that I could use a tow dolly for towing behind the motorhome. (my Accord has the same V6 and Transmisison as the FWD MDX) The rear wheels on a FWD vehicle simply trail along and are in no way attached to the drive train. If you use a tow dolly, you will be fine. You will want a tow dolly that has a plate that moves and/or wheels that steer so you are not putting undue strain on the steering components of the vehicle being towed. So, yes...read the manual and you will see that 4 up or FWD front 2 up are accceptable.
