highway or cityNot much better than my 2001 8.1 Litre Gas 4WD Quigley 3500 Express van.
It gets 12.5 - 13.5 MPG all the time trailer or no trailer!
All the time!highway or city?
Most that get one don't ever sell it...that combined with the low production numbers make them tough to find (and was a big part of why I built mine).
.I've seen several gas GMC van overlanders but have not seen any with diesels.
The Duramax your friend is talking about are the 6.5 and earlier versions. These 6.6 versions are very durable. There is a member with a dieselplace forum under van section, he has a 2006 duramax van which he uses as a work van and towes too. The van has 400k+ miles with original engine and transmission.I’m glad to hear the Duramax is working out for all of you.
A good friend worked for a tow company... he told me the Duramax they had kept blowing head gaskets. He had a low opinion of the Duramax. 6.0 Fords were even worse.... in contrast the 7.3 truck’s hour meter had been pinned at 99,999 hours for years, and it just wouldn’t die.
The 6.5 Diesels were Detroit Diesels I believe.Great looking rig. Who did the 4x4 conversion on it?
the 6.5 motors weren’t Duramax, they were pre the founding of the GM Isuzu partnership. It was either a GM in house or a Detroit Diesel, can’t remember.
