Yes on completely fill the radiator and run the engine.
Kids hard plastic pool will catch a lot of splashy coolant. 5 gallon pail will not fit under radiator drain, it’s too tall. And if you put a pail under there you will get a coolant shower each time you turn off the petcock to change pails.
Then xfer to buckets.
The easiest least mess way. Find the drain plug on the lower coolant hard pipe. Look at the hose coming out of the rad going to the water pump. Put a swimming pool under the drain. Open the radiator cap at the expansion tank. Unscrew the drain plug. Go have a soda. It will take a while.
Do yourself a favor and get some sort of powered transfer pump either one that works with your drill or a more robust 12 or 120v powered one. Your arms will soon tire of filling coolant into the fill port 7 ft up on the coach. If you try it by hand, you will need to figure out what to do for a funnel. There is a special cap/hose that will screw on the top of a coolant jug avail at any auto parts place.
