Do a 200-mile out & back loop on cruise control with same van weight from the same fuel pump (fill, and then refill; both times to first auto shutoff). and then report back.

I can see 30+ from my 9,000-lb CTD one ton pickup for extended stretches at the usual 58-mph & 1,725-rpm, but a trip has also a beginning and an end. Not just a middle. 25-27 is the likely number I’ll see by trip end given “nice conditions”.
