The major consideration is usually weight of the genny. Unless your sons are old enough, the Honda 3000 would be a bit tough to handle alone at 90 pounds. Two 2000's are easier for one person to wrangle on their own.
The next consideration is run time on a full tank. Our 3000 runs for 17 hours without AC, 6 hours for steady AC use.
We have a genny box in the bed of the TV. Once loaded into the truck at home, it stays put until the end of the trip. No lifting needed.
Found ours on Craigs List for $1100 barely used
