Sorry but I would have to side with the Mrs on this one. Floor plan is number one. Consider the time you may actually be going up a steep enough grade to slow you down vs the time you will spend parked and enjoying the floor plan. I left west of the mountains in WA state so we often goover the passes. I have a 34 foot V10 gaser pulling a 4000 lb Suzuki and slow to 45mph for 10 minutes or so. That is is no time at all compared to the total trip time. Now given that you would have more torque than I do, I have to come to the conclusion that she wins.
