The power rear vents are a valuable asset and after having the previous Caravan without power we particularly looked for this feature. No more having to stop to open or close them. We find that operating the screen demist setting, cycles the air conditioner and with the rear vents open a comfortable cab interior can be attained without full time air. Albeit with a little more road noise.
I am not a fan of manual shifting automatic transmissions. At least untill now. I found that the lever could be operated without having to take your hand from the stearing wheel and whilst I would not be inclined to do this normally, I found it very useful to use in the mountains with our small trailer, when early shifting to maintain revs, was advantageous. The closer ratios of the six speed were also great when doing this.
One should note that the rear of the van drops a little after being parked for a while (overnight) with the load levelling tow package option. This is quite normal and ride height is quickly regained after a short distance along the road. There is no compressor involved; the shocks transfer fluid to level themselves using suspension travel whilst in motion. I find this arrangement to be a higher quality ride than the previous model without this equipment.
