I want to take my 2004 S2K with me motorhoming. Dealer told me I can't tow (either with all four wheels on the ground or with a dolly), so I've ordered an enclosed trailer. My question is: Where do I have them place the tiedown D rings on the trailer floor (how far in from the front, rear and sides of the car) and where do I fasten the tiedowns on the car itself?
