Here's an update Toes,
My 2017 307 MKS came with a 10" I-beam and it is the same overall size as the 303rls.
I had ordered the 303 and the 307 had just come online. I pretty much switched my order, based on the "as built" specs and I liked the different floorplan with a desk at the rear for my laptop & photo toys.
It also came with 6,000 # axles, which gave it 3,000 # leaf springs and 16 " wheels.
Even the EquaFlex is the heavier 6K to 8K model.
The slides are within 100
#s of each other bc the frig isn't on a slide, it's on the rear wall, so evenly weighted.
Has a pin weight of 1,595 #, GVWR of 12,995 and a UVW of 9,875 # which gives
it almost 3,000 lbs of NCC.
Now, I will never carry even half that weight, but it is nice knowing the trailer is over-built, rather than borderline, IMHO.
Frankly, I am surprised it was not more popular from an engineering standpoint.
