"if i have to i will sreatch the m818 throw a tag under it and put a 18sp and something around 450 or 500 h.p. in it. i just need the 6x6 capability plus the cost effectiveness, cant beat allwheel drive on these farms".
if you are going to all that trouble and expense to build a heavy haul tractor, why not find a older 6x6 concrete mixer, pull the barrel, fifth wheel and air line it, you would have better length, a 8 to 13 speed, a very stout frame, a good size motor, very heavy suspension and drive line, off the shelf parts, better road speed on the empty haul, a power divider. all the 6x6 mixers that ive seen have air shift xcases and front drive
