I am sure you are correct on that.

Will be tough to get a good test drive, though, until someone builds an RV on one to load it down.

Robert Ryan mentioned the Motori 428 being around a while so pretty proven. Wiki lists it back to 2001 with a fuel delivery update in 2010. Also said Motori is owned by Fiat.

I wouldn't consider it a new engine. It has been in use for 5 years and is an upgrade on an engine that has been used for 15 years. Just new to the GM vans.

Plus there is a long warranty. I'd buy it if I wanted an RV on the Chevy platform.

The old engine must have been de-tuned for the van application. This same engine in my Silverado is 425 horsepower and 795 ft lbs of torque - it's a beast!

Sprinter is rated at 7,500lbs in the US. Exactly the same Sprinter, is rated 4,400lbs in Australia. So what the 2.8 can do is a mystery.

That's due to the opposite Coriolis force.
