I have been reviewing Eicher Pro 1090 truck for the past week,Eicher manufacturers has done its best and put on the maximum work on ace models,the Pro 1090 that i have been reviewing have a mileage about 7-8 kmph,but it keeps descending by time goes up, however the maintenance costs are very low,talking about the engine, It is having the enough torque for the last two gears with city rides,but in highways it gives its best.
