We just ordered a Sunseeker TS 2370 on a Ford transit chassis. What kind of mileage can I expect with this rig? My current motorhome is a Dynamax rev on promaster 3500 and gets 15 mpg. I'm hoping to ...

That is decent fuel economy. Too bad that chassis is offered only with a SRW axle. A DRW would have done the chassis wonders.
I've seen this comment regarding this chassis from you before and wonder why. The Promaster chassis is front wheel drive, and it would be silly to put dual rear wheels on a front wheel drive chassis to load the rear axle heavier. These trucks, when their axles are fully loaded, have about a 45/55% F/R weight bias. RGAWR on a Promaster is well under 6000 lbs. Single rear wheels handle these weights easily. If you bump that up to a 7K+ RGAWR on a FWD chassis, you're not going to go anywhere when you're fully loaded.
Now, the RWD Transit and Sprinter chassis, benefit from a DRW axle since they carry more weight in that configuration. But the DRW Transit does not have a wider rear track than the SRW, unlike your E350, so the DRW Transit will not have the extra stability a that the wider track of the E350 or 450 DRW.
