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

Had a gasser, would never go back. Not just the engine, the brakes, the frame, the interior, I can go on. But it is your budget. You must live within yourself. For 3-4 weeks a year, I would keep what you have. We live in ours 6 months a year 12 to 15k miles a year. Big difference.
