I think you would be disappointed with the power and the mileage. Below is a picture of my Mitsubishi-Fuso.
Advantages: Great manueverability, replaces a pickup plus an 18' trailer, good image, can trust the employees to drive it before I trust them to tow. Comfortable, drives like a car.
Great around town. Very peppy around town.
Perfect for customers with tight properties.
Great for toting sod, etc.
Fits in many parking spots.
Ice cold A/C
Good offroad versus pulling a trailer.
Rock solid reliable engine. Never missed a beat.
Disadvantages: No power on the highway. I mean no power. Top speed is about 68 mph. No passing power. 0-60 is measured with a calendar. Any uphill at all and top speed is 45-50 mph. No joke, its a road turtle. Semi trucks eat you for breakfast on the highway, they just cruise right past you even if you are floored. Rear axle is 5.73:1. These are city trucks.
Cab is cramped with more than 2 people. 3 is absolute max.
Poor automatic trans, replaced mine 3 times in 40K miles.
Don't get the Aisin-warner auto get the Allison.
Fuel economy is 10-11 mpg diesel city or highway, loaded or unloaded.
I bought mine mainly because I work out of my house and it fits in my driveway.
I am seriously considering the Chevy c4500 crew cab duramax as my next truck.
If you must get the Fuso get the 175 HP four cyl. It is rated at 347 lb-ft torque versus only 275 lb.-ft. for the 145 HP motor.
Don't plan on towing heavy loads often- the Fuso can barely get out of its own way unloaded.
