While it does not give info on towing capacity, it has a 2.2L, 4 cylinder diesel. For comparison sake, a 09 Ford F-250 diesel (smallest Ford diesel truck) has a 6.4L 8 cylinder engine and has a maximum loaded trailer weight of 12,500 lbs. I don't know enough to adjust for engine displacement and cylinders but the Indian truck is roughly 1/3 the engine displacement and half the cylinders. The laws of physics, thermodynamics and a whole bunch of other laws (including those administered by the EPA) apply to both vehicles so one would suspect that the Indian truck would have modest towing capacity, perhaps not enough to tow a CD-22 set up for cruising.
Another comparison point is a Honda CR-V which has a 2.35L, 4 cyl. gas engine and a towing capacity of 1500 lbs. While there are many factors that limit the CR-V's towing capacity including transmission and construction, I suspect that the engine is partly a factor.
Perhaps one of the gear heads on the List can take a better guess at towing capacity.
Also, remember that virtually all of the light diesel engines sold for truck and marine propulsion applications these days are common rail as is the engine on this truck.
