Tank sizes run from 5,000 litres on the NQR81K to 16,000 litres on the 6×4 FVZ34. Most county and contractor water bowsers sit in the middle, on the FRR90N (8,500 L) or FVR90 (11,000–12,000 L). Fuel tankers use the same chassis with an epoxy-coated tank and a metered dispensing unit.
Body options
- Water: stainless steel, or mild steel with cold galvanising
- Water: PTO pump, high-lift pump, internal baffles
- Fuel: epoxy-coated mild steel with metered dispensing
- Suction and delivery piping on both

GVW from the manufacturer’s brochure, as on each model’s page. Typical tank are typical body-builder figures from the Isuzu East Africa Truck Application Guide, March 2022; the body built for you may differ. What a truck can legally carry depends on the body fitted, so check your load in the payload calculator or ask TMD.
Good to know
- Internal baffles stop the load surging under braking. They matter more on a tanker than any other body.
- Fuel tankers carry dangerous goods. Plan the licensing and markings with the body builder before the tank is built.
Questions
What buyers ask
What is the biggest Isuzu water bowser?
The FVZ34 6×4, with a typical 16,000-litre tank. The most common bowsers are the FRR90N (8,500 L) and the FVR90 (11,000–12,000 L).
Which Isuzu is best for a water bowser on rough roads?
The FTS34, which is four-wheel drive and takes a typical 7,500-litre tank, for routes where a 4×2 bowser would get stuck.
Stainless steel or galvanised tank for water?
Both are offered. Stainless costs more and resists corrosion best for drinking water; mild steel with cold galvanising is the lower-cost option. Ask TMD which suits your water source and budget.
