It's an easy job.....just like anything else with a motor home, it's a lot of fluid to deal with. Turn your heater on, get the engine warm and drain. Now here is where some disagreement comes in. If it's dirty it might need two flushes. The first flush you can use water form the hose. Get it warm and drain. The second flush, many recommend using distilled water. Some will use distilled for both flushes, but in your case....since it's clean....you could probably get away with one flush.
I used Final Charge when I flushed mine. You can by Final Charge in the concentrate or 50/50. If you use the concentrate, you mix it 50/50 with distilled water. When I did mine, I put in two gallons of concentrate and then the rest was 50/50. The two gallons of concentrate was added to mix with the water caught in the engine and plumbing.
