This was with 4 people in it. Getting on I64 in Maryland somewhere between the WV line and Cumberland those steep off ramps resulted in a lot of buzzing and vibrating and we thought we were going to have to get out and push up the ramp.
My mileage doesn't drop in the mountains, but I can stay in OD also.
We made the mistake of buying a minivan a few years ago. There is a steep hill coming down route 7 between Terra Alta and Kingwood in Preston county. By the time we got to the bottom and up the other side in Kingwood I would have to stand both feet on the brakes to get us stopped. Since I had to travel that hill a few times a year I would have to replace the brakes and rotors every year by the end of summer.
One thing I have learned is to never buy a front wheel drive vehicle, they just don't hold up under tough situations.
