Sorry but that simply is not true. My 2012 Nexus sits on a 2011 E-350 chassis with a GVWR of 11,500#. The 2012 and newer E-350's have been bumped up to 12,500. Even at 11,500 mine comes with 3,368# of payload. Fully loaded for the road we weigh 10,050 leaving me an additional 1,450# available that I will probably never use.
The 450's have more GVWR, I think they come in at 14,500 and a 4:56 rear end vs the 4:10's on the 350. You will get a rougher ride and worse mileage with the 450 but if there is a Toad in your equation the 450 is probably the better choice.
IMHO: Don't sell the 350's short. On C's 24' or less the 350 is the way to go, better of ride quality/handling and mileage yet still come with more than enough payload.
As always.... Opinions and YMMV.

According to the 2008 Ford spec sheets, the Super Duty E350 Dual Rear Wheel cut-away chassis was available in three different weight ratings, 10,000, 11,500, and 12,500. Apparently Nexus used the 11,500 pound 2011 E350 chassis. Phoenix USA has always used only the 12,500 chassis on model 2350 and 2450 since the current day E350 chassis came out in 2008..... with rare exception. Many months ago, Phoenix got a super deal on a yard full of lesser duty E350 chassis from a local RV company that had gone out of business. Phoenix passed the savings over to their customers if selecting one of those chassis for lighter model applications. In 2010 Phoenix had the same opportunity with a yard full of Sprinters, offering a Sprinter version at the cost of an E350. Phoenix is a creative company, trying to reach people with lower budgets when the opportunity presents itself.
With our earlier 2007 DRW 11,500 6.8L E350 chassis, we too have more than enough payload capability. After being loaded up on trips including a full tank of fresh water, I still have an extra 1300-1400 pounds of margin, though not necessarily distributed properly. I think our 2" rear sag is strongly influenced by the weight placed on the rear frame extension. My 40 gallon fresh water tank sits against the back wall & rear bumper. The company has since relocated the fresh water tank forward so maybe the newer models lost the sag. I would research it more before making a decision on an E350 or E450. I do lean toward the E350, but would want to research deeper to make sure.
The E350 advantages over an E450 are primarily a 10% increase in fuel economy and a softer ride, both extremely important to me personally. Is the E450 better for the wider rear axle stance, higher ground clearance, excessive payload ability, and hydraulic power brake system? If going with a Quigley 4x4 conversion, or pulling something serious like a large boat or multi-horse trailer, I'd go with the E450 for sure. But for typical RVing with our Jeep Liberty tow vehicle, I do lean toward the E350.
