If you're running "one heater on each leg", you should use two single breakers rather than a tandem. You can easily make sure each breaker is on a different leg. If you're using a tandem breaker with two potentially unbalanced 110v loads, you can cause problems.
Taking the single out and adding a tandem will put each heater on its own leg. He will not need two single breaker since the tandem will give him two legs/circuits. Balance will be no different than having two single breakers.
Are you sure about this? Most tandem breakers I've handled only attach to one load center bus.
Edit: This may not be true of a 50 amp RV load center. I use a residential load center in my trailer so don't have a specific RV load center.
And, there is no reason not to balance the amount of potential draw between the two legs of the service. Why would you want to pull everything off one leg?
Your making this more complicated than it needs to be. He is removing a single 15 AMP breaker and replacing it with a tandem giving him two 15amp 120 volt circuits. The tandem will now be two singles using one single pole breaker slot. The circuit breaker bus branch/bus stab does not play into this at all.
