Older DP or Newer Gas Class A? What would you do and why?

Diesel are quite because the engine is in the back. I have heard some folks here say they have gone back to gasser. It boils down to budget and how much you will use it. My old class a was a gasser, it sure was noisy and under power. That did not bother me. My current setup is worse and I hate it. I thought about getting a diesel truck, but I really don't want the repair bill. So, I am keeping my setup for now.
