The dry tongue weight on this model is 350 lb which is 9 percent. So with a loaded weight of 4700 the tongue weight should be around 425 lb.
Nonsense.  Doesn't matter what the so-called dry tongue weight is listed at ... fact is, this trailer loaded and ready to camp is going to weigh 
at least 4500 lbs but more likely closer to 4700 to 4800 lbs even with careful loading.  14% of 4700 lbs is 658 lbs ... which corresponds quite closely with my own Coachmen Freedom Express which is a bit lighter than the OP's Minnie, typically averages ~ 4500 lbs loaded and ready to camp, and which averages a gross tongue weight in the 600 to 625 lb range depending on the cargo I'm carrying at the time and how much content may be in any one of the three holding tanks.  No way, no how will the OP be running just 425 lbs of gross tongue weight ... no way.
