I have not looked at the TerraPro's specs, but many LCF type of trucks are limited in their engine offerings. This is due to physical limitations and cooling capacity.

Mack builds a very good chassis cab, but would it be worth the extra money to have the cab extended for more seating when you could just purchase a fire apparatus chassis from Spartan or Hme without all the added cab modifications !

We looked at the Terrapro last year as a potential tanker chassis.
They are available with plenty of GVW & enough Horses to work. The only holdback was price. Stock chassis was in the same market as base level Spartan Ferrara or HME custom cab chassis.
By the time you had a custom one off cab made for it you would be well into mid-high end customs in price and have an orphan one of a kind when it came to parts.

IH does design/test to a higher standard though than Freightliner. Another reason to like the IH chassis (no SCR BS and have Roll Stability system).
Roll Over Protection Ė Why SAE J2422?
The International cab structure was developed to meet the roof strength requirements of the SAE J2422. These requirements were developed with Navistar engineers working with the Society of Automotive Engineers to
develop a test to promote occupant protection in the event of a rollover accident scenarios.
SAE J2422 was chosen over the European standard roof strength test (ECE 29) for two main reasons. First, the SAE test procedure recognizes the forces that can compromise the structural integrity as a truck rolls onto its
side, before it comes to rest on its roof. The ECE 29 test only applies a vertical load. Second, the ECE 29 also applies the load to the roof uniformly by a preformed platen, where the SAE test requires a rigid flat platen which
results in a more severe test. See page 3 for additional information on SAE J2422 versus ECE 29 testing.
The International crew cab, extended cab and standard cab have been tested to meet the roof strength requirements of SAE J2422.

I'm not sure how many builders that still construct enclosures for crew to ride in behind a commercial cab have actually tested their enclosures for compliance.
We all know a 4-door is compliant direct from IH or Freightliner, however, the aftermarket 4-doors that were available for KW and Peterbilt from Bentz are not tested for rollover integrity, just seat and seatbelt standards.
Here's the NFPA standard as well:
NFPA 1901 - 14.3.2 - Cabs on apparatus with a GVWR greather than 26,000 lb shall meet the requirements of one of the following set of standards:
(1) SAE J2420
(2) ECE Regulation number 29
