With the 28,000, the 3208 will be fine. If you could manage the 42,600 with your current gas engine, the 3208 will be much better (but it will still be a load).
It's still not going to drive like a car.
I guess it comes down to how fast do you want to go, and how much fuel do you want to burn to get there.
a 3208 will be better than your current gas rig. A 8.3 cummins is a little more torque than the 3208. A m11 is even better. A N14 at 350hp will drive like a car with 28,000 lbs. My 500 hp detroit with just the lowboy (empty/no load) will sit you back in the seat when you get on it at 34,000lbs ( I always think "rocket ship" when I kind of get on it empty).
You're still going to have to down shift on hills, and drive it similarly to what you do now, it will just be a little faster. I would guess hills that you pull at 15 mph now, you could pull at 25 with the 3208, but your not going to pull it at 45-50.
My shop hill is about a 19 percent grade. Its around 3/4 of a mile long the one direction, and I would walk it in 3rd gear (9513 trans/ 6.14 rears) with my 3208, with the 50,000lb crane. I ran it with the 3208 for 6 years, and that's what both cranes had in them from the factory, and the one crane has been in this area its whole life (its a 1977).
I think my terrain would be similar to yours, we have a lot of short steep hills, you probably have some longer hills than I do, but nothing like they see out west (8 percent grade for 11 miles etc.). The 3208 you are still going to have a line of cars behind you on a big hill, but if you want to roll with traffic, you will have to go bigger in hp in really steep hills. In my area- the dump truck guys who want to roll- all run big block 3406, 855/n14 cummins, detroit 12.7, and they run with traffic on the hills at 50,000lbs.
I think I would take a 3208 before a 3126. Easier to work on, and less expensive when you do. No fancy equipment to run overhead, no need to have a computer for diagnostic. 12v fuel solenoid and a start signal wire is it. I had a 3208 get one of my operator's home, with 2 pistons in pieces (dropped a valve- pieces from it went to the next cyl- but it was still running- sounded terrible, but it got home).
We have mostly narrow 2 lane (some more like 1 1/2 lane) blacktop in my working area. No shoulders. If a electronic motor has issues, you are stopped right there. I don't have a parking lot, or shoulder, or place to pull off. Generally a mechanical motor, will develop a miss, or no power etc, but its going to get you home. No sensor throwing a code and stopping you while the motor itself is fine.
For ease of diagnostic, and getting back running, I'll take a mechanical motor over a electronic motor every time. But my situation isn't the same as everyone else's. I don't run a terrible lot of miles, I'm not more than a hour or so from my shop, and I work on most stuff myself. I'm not worried about milage/ fuel usage very much, and I bid no work and charge by the hour.
but it weighs loaded 28000, not 80,000.
, I weigh 42600 combined.

In 2018, which would you rather have?
