Our Ford L9000 Dump is getting to the point where the yearly repair/maintenance costs are really getting up there so I am looking for a possible replacement. I found these 3 trucks and am wondering why they are still around.... bad economy? Or the fact that the have the smaller sized engines instead of the usual C13 Cat or similar Cummins? http://www.usedtrucksinusa.com/details.php?MID=14854 http://www.usedtrucksinusa.com/details.php?MID=14855 http://www.usedtrucksinusa.com/details.php?MID=12686 I really like these trucks and the fact that they are "new" I priced out a similar 2012 and wow is all I can say. Is the smaller motor something to be concerned with and possibly why they have been sitting for 4 years? We have a Triple axle T50 trailer that we move our case CX160 and Doosan DX180LC around on.... is it going to struggle pulling these 40k pound machines around? I really hate having underpowered equipment. Just looking for some insight.
