We picked ours because it had more cab room and drove better. A lot depends on how much the unit weighs. Ours scales at 9,020 lbs. fully loaded with both of us on board. We have a well-documented 12.1 miles per gallon. I have recorded every tank fill on a spreadsheet that adds all the gallons burned in total miles travelled. So "j-d" has a point, if you have the same engine in a 14,500 lb unit, you might struggle up some hills. With our lighter unit, we have been able to accelerate up mountain road.
...Now, if the Chevy is old enough to have a 5.7L V8... that engine is not in the same league as all the others I've mentioned. I wouldn't suggest that one for anything but a smallish B+.
The 350 cu inch 5.7L Chevy engine has been around for years. I owned a 1970 Chevy pickup with essentially the same engine. Drove that one close to 200,000 miles without any problems. It didn't get as good gas mileage as the RV. That 4 barrel carb would pour the gas into the engine. Most owners call the engine bullet proof.
