Re: Looking to Trade our 15 Altitude for a 16 High Altitude.. Engine Advice requested
After a full week of owning my new High Altitude V6 I have no regrets. Except for low end peppiness the V6 feels just as quick as the V8, it's a more quiet driving experience, drives/handles and feels significantly lighter (my V8 Summit felt like a tank), better steering (I guess V8 is getting electric steering for 2016), V6 doesn't recommend the use of mid grade fuel, so far at only 230 miles on the odo and in the dead of winter I'm already beating my best ever mpg that my Summit got in the summer with 5000 miles on it (and that's driving moderately for breakin as recommended in manual). Initial cost will be $3000+ less.
Overall I am extremely happy with my V6 HA and even though that is neither of the engines you asked about, I have to recommend it after having experience in both.
