IMHO, that's quite expensive for a 100hp motor without controller. I'd check for industrial AC motors also, those should be had for half that nowadays. Look for Siemens 1PH7 186 or 1PH7 225 or similar. The latter is available with up to 125kW S1 power.

You would need very high voltage (600V) to make use of the full RPM range, but OTOH, you're going to need lots of batteries anyway to get any decent range. And the higher the voltage, the lower the amperage.
Page 152 of the manual shows 1PH7 186...F.. which is rated 74kW continous at 1500RPM and may go up to 4500RPM. It will need 170A to deliver this power, and can take twice that for short periods of time. S1 torque is 470Nm from zero to 1500RPM. It will need 330VAC at 1500RPM, that should be around 470VDC input voltage for the controller.
Now, will 100hp do the job?
100hp continuous for that big a vehicle (30.000lb, 13.6t) might be okay for city cruising and without trailer, as long as you can use low gear. It may be a little low for highway. But as electric motors can deliver at least twice their nominal torque for short periods of time, you might be okay. Check the available torque of the diesel engine and compare that to the torque of the electric motor. Then check the motor RPM at the speed you're cruising.
The batteries to supply the energy for this kind of application will be the bigger part. I'd guess 40kWh pack capacity as the absolute minimum, triple that for any useful application beyond testing on the driveway.
Just my opinion, it's my first post here. I've done nothing in EV yet, but I'm mechanical engineer and do (among other things, of course) power calculations for industrial appliances for a living.
