Whatever a 5.3L Vortec does, the 2.8L Duramax can do. I have even seen an S10 (the Colorado name is not used in most of South America for political and soccer-related reasons) with this engine pulling a 5th-wheel trailer. As far as a rig like your ambulance goes, remember other trucks with a similar GVWR tend to use 4-cyls ranging around 4 to 5-litre and are much less rev-happy than the 4-cyl Duramax, which with a suitable gearing does the job just as well as those do.
