Existing Single Rear Wheel E-350 has a track width listed at 72.1 inches.
Typical Transit Dual Rear Wheel chassis has a track width listed at 65.7 inches.
In addition, SRW chassis of similar overall width allow rear leaf springs to be set further apart for added roll resistance. Should have greater stability.
When designed properly, I’d take SRW over DRW pretty much any time with very few exceptions.
