That is decent fuel economy. Too bad that chassis is offered only with a SRW axle. A DRW would have done the chassis wonders.
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 SAFELY when you're fully loaded.
Shhhhhhh. Don’t tell GM that.
Clicky, clicky, clicky……..
Wouldn't the rear leveling airbags push some of the weight to the steering axles similar to a tag axle?
Not to mention the heavy 455 and transmission sitting on top of the steering axles
