I also appreciate the locations of the furnace and fresh water tank that make the 03-04 models the 2350 storage champs.
If you want to go any further with handling mods bolt on a Hellwig 7085 rear sway bar and thank Mr. Ron Dittmer.
The placement of the furnace and fresh water tank in our 2007 is like the earlier 2350s. You are right in that makes them storage champs. But it comes at a sacrifice to handling.
Every E350 chassis Ford made prior to 2008 never came with any kind of rear stabilizer bar. If you have one in back, it was added after the fact. So if you own a 2007 or older E350 chassis, look underneath in back. If you don't have one, you will surely want to get one. A rear heavy duty Helwig does wonders.
And as for the wimpy poorly designed front stabilizer bar of the same era (with end grommets) is concerned, replacing that one with a heavy duty Helwig makes another big improvement in handling. If you do nothing else but those two changes, you will have covered much.
When your current shocks get tired and worn, replace them with heavy duty Bilstein shocks and then you made another significant improvement.
The E350 chassis was used for the shortest PC models which by design have poor ratios of wheel base to over-all length. The suspension upgrades I mentioned combat that condition fairly well.
It seems model 2552 with the E450 chassis has the ideal aspect ratio. With the improved OEM Ford stabilizer bars introduced in 2008, handling issues are minimal by comparison to unmodified 2007 and older E350 PCs.
