I've seen a lot of the RWD 1500 pickups from the uhaul fleet with the G80 as installed going a few years back. So would not surprise me the vans are that way too. Certainly a better option than what the OP is looking at.
The older 4.3 vans had 200-220hp so not a lot of power. The 2014+ 4.3 is around a 300/300 motor, as the 4.8 V8 is. The 5.3 depending upon year ranges from 320'ish before 2014, and 350+ after 14. 14+ motors the mpg is increase upwards of 25% vs previous models. depending upon budget, a 14 or newer is a better option.
