A Cummins B-5.9 is to large in my opinion. You will need a dog house built into the spacious 3 man cab, and its HEAVY.
A B-3.9, CPL 857 (not all 4BTA's are CPL 857) will give you 130 HP, more that enough to do the job. Charge air boost requires large piping to the front and there is not much room. Suggest JWAC (Jacket Water after cooler) fits right on engine and does the job. You need to keep the RPM's at cruise down to 1800 to 1900 max.
To do so you need a 5 Speed OD such as a NV-4500HD driving into NP-205 T Case, driving into 4.89 ring and pinions front and rear.
Then with the added weight, you need to beef up the front suspension, Add Power Steering and Power Disk Brakes on all 4 to stop the beast.
This build is VERY costly
