Sorry, I just saw your question. My truck is a long bed, 8', dually. Dodge's quad cab isn't a full crew cab so it is probably a little shorter than yours. I have my hitch out now, but, I can probably come up with an overall length for you.
I did some conversions and your truck wheelbase is 165" and mine is 160". My overall length is 55'-9" so yours would be 56'-2" or 17.145 meters assuming that the front overhang is the same as mine. This would also be if the hitch was centered over the rear axle which they are usually a few inches forward of. Looks like it would be close but still under the 17.5. I'm planning on taking mine to the dealer to have the rubber gas line to the refrigerator and stove replaced since it is kinking with the slide in next week and I'll put a tape measure on it then.
