Gjac, It's my belief (and I could be wrong) and I agree with you that older systems are more reliable! I would like to buy a new coach and I'm a die hard Winnebago guy, but I would be fearful to buy a new Winnebago from what I'm hearing from posters. If I was to upgrade it would be a DP around 2007-2008. I don't like the new gassers with Ford motors after buying a new 1999 Ford V-10 Triton that spit out spark plugs. And, I don't know why Chevy small block motors aren't being used those New Generation motors can put out up to 600 HP?
