Weighing the RV to make sure your not over weight, four corner weight preferred,( packed and full of fuel for travel) and setting your tire pressures according to the tire manufacturer's inflation charts. Is the next step.
Can't begin to balance the load if you don't know your starting point.
If the weights show an imbalance of over 200 lbs. side to side consider shifting cargo around to compensate, moving weight front to rear would depend on how close you are to you max axle weights, would be nice to be the same amount under weight front and rear , but not always possible, some of the heaviest things can't be moved . Fuel tank for example.
