if you hadnt noticed, deisel small rigs have almost dissapeared from america.small vehicles have to operate under stricter emission regulations than heavy vehicles. remember the 80's? rabbit car and trucks, 50 plus mpg, my gpa had some of them. luv deisel trucks, 35 mpg, i had one. ford tempo deisel,40 plus mpg.gpa had one of those also. deisel jetta . all those have gone.
i have been told the epa figures pollution amount per gallon of fuel consumed and doest take into account that the gallon burned may of went 2 or 3 times as many miles as a gas rig.thats ingnorant if its true and may explain why they disappeared. not to mention lots of people not familiar with deisel engines are scared of them. oh it wont start, they say in the winter.that can be true if the proper care and maintence is not done. i had block heater and a timer on mine that kicked in a couple hours before i went to work.
another thing to take into consideration is that basically detroit has ruined the rep of deisels.i would not own a diesel truck made nowadays.they dont go 200k like they used to without expensive work done on them.sometimes work so expensive the truck is not worth fixing.
