My previous coach was a 400/1200 ISL at 32K. I chipped it to 450HP and it was a rocket, even when towing. The new coach is a 450/1250 ISL weighing in at 37K and is a dog on the hills. It's taller, heavier and dragging a tag axle.

With that much torque it should do good in the hills, is it the low HP or what, my setup plus towing total weight is 26,500 lbs same HP as yours but under half the torque and I am impressed how it handles the hills and I thought mine was going to be a dog.
