What I have now I bought when I just got started and it tentatively fit my needs but has been modified.this is a factory 4 axle not a stretched road conversion also it is double framed. The factory steer has long since been removed. And replaced with a 23k steer. Also gone thru the factory to get re certified. The bunk sucks but When I started it was just me and the dog. The 46 rears are holding up pretty good.the 2 speed gear ratio is great. But got a lead on doing tower sections and I think they will be to light, And don't want to tear something up. It does have the 18 series drive line. Motor wise I have no complaints. Trans wise I would like a few more gears. I do have an 18 but would like a 4 speed aux behind it to get real low or cruise at low rpms empty. I know what I want in a truck and next one is going to be spec'd that way if I can get one new. I am not going to get a redone star car the shaker redid. It would either be a 357,389, Or a wide hood T800. I know Titans aren't cheap. Then again what truck is. I do alot of oil field,jobsites,and Mines. my road time is 90 to 95 % but when I go off road I go places the road guys are scared of, Without fear of OMG you want me where or this truck does not go off road. If I wanted that I would pull a box. I originally wanted a Mack, they had there own priorities on what they wanted to sell. Also had a problem with people wanting to deal.Bought what I had to to start out. But it had the motor,Trans,and rears I wanted. My biggest thing is the sleeper size. I need a workhorse not a beauty queen, And if Mack can't or won't build it someone will. Don't take this as knocking Mack I grew up around them and been around them for a long time. But had to do what I had to do when I started out
