I did LOTS of research on the internet, then lost out to TLOML ( so now we have a 25 footer, not a 32). If you are trying to save some money, I would take a hard look at the GM 6.5 Turbo diesel. They have a bad reputation, and as a result seem to sell for less. The big problem is the electric throttle. The gizmo mounts to the side of the electric fuel pump and has a bad habit of overheating the pump, causing pre-mature failure of an expensive part. Of course there is now a kit to mount the gizmo elsewhere, solving the problem. The second issue is lack of maximum output compared to Doge or Ford. The GM runs only five pounds of turbo boost, while Navistar and Cummins run 15 pounds. Somebody re-built a GM ( changed the comperession) and ran it at 15 pounds of boost. It then matched the other two for maximum output.

Driving empty most of the time the lower output wouldn't be a problem. Parts should be available for a long time as this is still the standard engine for the AMG Hummer.

Just my 2 cents worth.
