Ashok Leyland AVTR 2820-6x4 3900/20m3/Box

Twenty cubic metres on a 3,900 mm wheelbase. Ashok Leyland sells the same 20 cubic metres on a 4,600 mm wheelbase, so why does this one exist? The answer is your site, plus one piece of geometry nobody talks about.

The Short Wheelbase Buys Access. It Also Buys a Deeper Body.

A shorter frame carries a shorter body. Fit 20 cubic metres into a shorter box and the box gets deeper. No way around it.

Use this page's own internal width of 2.3 metres. On the 3,900 mm frame the body runs about 5.2 metres long, so the sides must stand roughly 1.67 metres tall. On the 4,600 mm frame the body stretches to six metres and the sides need only 1.45.

That is around 220 millimetres of extra sidewall on this truck. Same cargo, carried higher.

Most days it makes no difference. It makes a lot of difference the moment you raise the body.

A loaded tipper with its body up is at its least stable. On soft ground, or a bench with a slight cross-slope, the taller box carries the load further from the centreline as the tip angle steepens. Tippers roll during tipping, not during driving. That is the trade.

You get real access in return. Tighter turning, easier reversing between stockpiles, better placement in a confined quarry. If your sites are cramped, this variant earns its place. If your ground is uneven, think hard.

What 20 Cubic Metres Actually Holds

Volume is not payload.

The truck carries roughly 12,500 kg once the body is accounted for. Aggregate weighs about 1,550 kilograms per cubic metre, so 12,500 kg of it fills eight cubic metres. Dry sand, much the same. Wet sand, less.

Your body holds twenty.

So you fill two fifths of the tipper and stop. The weight limit arrives long before the brim. The other twelve cubic metres ride empty, and on this variant they ride empty up high.

Coal is different. At around 850 kilograms per cubic metre, 12,500 kg spreads across nearly fifteen cubic metres, and the big body finally earns its keep. Fly ash and light spoil behave the same way.

Buy this truck for coal, fly ash and light bulk on tight sites. For sand and stone, the 16 cubic metre variant sits on the same wheelbase, carries the same weight, and keeps its load lower.

For reference, 20 cubic metres is about 7 brass.

A Payload Number That Does Not Add Up

The spec sheet says kerb weight 15,520 kg, payload 17,500 kg, GVW 28,000 kg.

Add the kerb and the payload. You get 33,020 kg on a truck rated for 28,000. Something is wrong by five tonnes.

The 17,500 kg belongs to the bare cab chassis, before any body exists. It has been pasted onto the body-fitted pages. Ashok Leyland's own 2820 RMC, on this platform, rates 12,740 kg once its mixer is on.

Plan around 12,500 kg. Read the figure printed on the registration certificate before you take a contract, because that is the document the RTO weighs you against.

Engine, Brakes and What the Spec Sheet Gets Wrong

The H-series is a 5,660cc six-cylinder BS-VI diesel. Two hundred horsepower, 700 Nm, six-speed gearbox.

Two errors sit on this page today. The description claims a 9-speed gearbox and a 5.76-litre engine. Neither is right, and the spec table above it contradicts both.

Two hundred horsepower is the lowest rating in the class. The Tata Signa 2823.K and BharatBenz 2823RT come in near 230 for money that is not far off.

Braking is the strongest thing here. Full air dual-line, ABS as standard, an anti-roll bar and reverse parking assistance. Ashok Leyland's lighter trucks skip ABS entirely.

Gradeability is 43 percent. This page currently claims 48, and the 4,600 mm page claims 64. Neither holds. Gradeability depends on power, weight and gearing, and none of those change when you swap a tipper body. Work with 43.

Top speed is limited to 60 km/h. The engine needs AdBlue.

Price in 2026, On-Road Cost and Who Should Buy

Ex-showroom sits near ₹34.50 lakh, though the seven AVTR 2820 variants are published from ₹31.80 lakh to ₹40.24 lakh. Get the figure for this exact wheelbase and body. Road tax, registration, tipper insurance, permit and fitness add ₹2.5 lakh to ₹5.3 lakh, so budget ₹37 lakh on the road. At ten percent down over five years, about ₹66,700 a month.

Then the fuel. Two to four kilometres per litre means 15,000 to 24,000 litres a year at 60,000 km. Diesel will outspend the purchase price inside two years, and that, not the sticker, is what decides whether this truck makes you money.

Buy it for coal or fly ash on confined sites. Buy the 4,600 mm version if you have room to turn, since it carries the same volume lower down. And look at the Tata Signa 2823.K if you want the extra 30 horsepower.
