My fire station has a E450 horton. We are looking at getting a new one,but some of are new truck commitee is thinking of going with the medium duty chassis reasons, is that on are e450 it has brake problems of heating up and the second is the cab is very tight when driving with gear on or gear off. second is visablity in the intersections is poor,and i dont like the way it shifts and the power going up hills. Where with the medium duty you are up higher and have better view in the intersections and brakes are bigger so it can handle the box whieght better plus there is more room in the cab and you can put a bigger motor in it. but we are going to stay with horton and keep the horton box size that we have this will be are first time buying a new truck and keeping the current truck for a back up are current truck is 9 years old..........so, what does every one think e450 vs medium duty chassis.................
