Two E-Series advantages not previously discussed are much larger gas tank at 55 gallons (or 40 for SRW); although downside is that larger fuel tank is required due to lower fuel economy. Still, it provides greater driving range, and also longer generator run-time when boon-docking.
The other is a lower cab roof height which makes it easier to climb into Class C over-cab bed, and also provides more headroom in that bunk area. Downside is inferior visibility for passengers riding in back of a Class C.
Not suggesting these advantages offset older design compared to Transit and Sprinter; just saying it’s not black and white. The body-on-frame design with heavy-duty engine, transmission and axles is appealing in its own way, even if ride and fuel economy are not quite on par.
