I would never consider a carbureted engine because I had a motor home with one. I sold it six years ago in 2007. The ethanol in all of today's gasoline had me replacing a particular diaphragm that was expensive to purchase and a pain for me to replace. I had to do that every-other year.
Another consideration is that fuel injection is computer controlled. It does good compensating for high altitude conditions for maximum power with thinner air. It also does better starting the engine at high altitude. Drivability will be much better when climbing mountain byways.
Other considerations is that carbureted engines are old chassis using other old technologies. They will have rear drum brakes that will need adjusting on occasion and no ABS. They won't have air bags and other improved safety features. Many will have weakened frames from fatique and rust.
I'll never go back to a carb or any chassis older than around a Y2K but that is a personal opinion. Obviously others here feel differently.
