The biggest pro to using one valve stem to maintain air pressure in an air bag kit is that you always know that both bags will have an equal amount of pressure in them. If you have an application where equal pressure on both sides is always the norm then that makes things simpler. Plus you only have to drill a hole for one valve instead of two on your vehicle.

The only real advantage to having two is that if you do need different pressures in either side you would be able to with that setup.

Most of our air bag kits come with two valves. If you wanted to run just a single valve you would need a union tee like part # F3025-1.

Then carrying a camper on the truck and you go around a turn dosen't the air in one bag get pushed into the other bag if you use only one air valve. Wouldn't it be safer if the airbags was with separate air valves so this would not happen.

What you're saying is correct. With a single air valve there's nothing preventing air from being pushed to one side or the other during turns. Unless you have a really uneven load in the camper though, this isn't really an issue since the air will balance back out once the truck is straightened.
