Tri fuel generators run on gasoline, propane or natural gas, which makes them backup machines at home first and power sources for big rigs second. At the campsite, the gas and propane modes matter most, since natural gas lines are rare.

Six tri fuel units are compared here, all in the 9,500 to 20,000 running-watt range. They were weighed on listed watts per fuel, outlet panel, tank size and CO protection, and the guide is honest that these suit large rigs and base camps rather than tents.

Why Each Pick Made the Cut

Best Value Tri Fuel· 1 of 6

DuroStar DS13000MXT 13

Danny’s Take

A lower-priced route to tri fuel flexibility for big rigs and home backup.

Best for

Large RV on a budget
Check price on Amazon for DuroStar DS13000MXT 13 (opens in a new tab)
DuroStar DS13000MXT 13

Why it made the shortlist

The DuroStar DS13000MXT is a 13,000-watt tri fuel generator with a 500cc engine and remote electric start. The listing names a fuel selection knob, a transfer-switch-ready 50A outlet and a CO Alert that shuts it down when fumes are detected.

It costs about a third less than the DuroMax XP13000HXT at the same 13,000-watt and 500cc spec.

It suits large-RV owners who want gas, propane and natural gas backup at home as well. The 50A outlet matches a big motorhome inlet.

Key dimensions & specs

  • 13,000W, 500cc, tri fuel
  • Remote electric start
  • 50A outlet, CO Alert

Pros

  • Remote electric start
  • 50A transfer-switch outlet

Best for

Remote start convenience
Check price on Amazon for DuroMax XP13000HXT 13 (opens in a new tab)
DuroMax XP13000HXT 13

Why it made the shortlist

The DuroMax XP13000HXT is a 13,000-watt, 500cc tri fuel generator with push-button and remote start, a CO Alert and a fuel selection interface. The listing says the panel includes a transfer-switch-ready 50A outlet.

It matches the DuroStar DS13000MXT on 13,000 watts and engine size, and its listing names a wider outlet range. The Westinghouse units lean on tank size, while this one leans on start options.

It suits camp organizers and motorhome owners who start the generator from a distance. It doubles as whole-home backup.

Key dimensions & specs

  • 13,000W, 500cc, tri fuel
  • Push-button and remote start
  • CO Alert shutdown

Pros

  • Push-button and remote start
  • 13,000 watts for whole-camp loads

Best Safety Tech· 3 of 6

Generac 12

Danny’s Take

A Generac with a CO sensor and voltage regulation for large rigs.

Best for

Safety-minded RV owners
Check price on Amazon for Generac 12 (opens in a new tab)
Generac 12

Why it made the shortlist

The Generac 12,500 delivers 9,500 running and 12,500 starting watts, with a 500cc engine, automatic voltage regulation, COsense carbon monoxide shutdown and electric start. A 7.5-gallon tank runs up to 9.5 hours at 50% load or 14 hours at 25% load.

Cons

  • Lower running watts than 13,000W units
  • Tank runtimes assume part load

The Catch

Runtime figures are at part load and will be shorter under a heavy load.

Best Runtime· 4 of 6

Westinghouse 14500 Peak Watt Tri-Fuel Home Backup Portable Generator

Danny’s Take

The runtime pick for base camps and big rigs that rarely refuel.

Best for

Long base-camp runs
Check price on Amazon for Westinghouse 14500 Peak Watt Tri-Fuel Home Backup Portable Generator (opens in a new tab)
Westinghouse 14500 Peak Watt Tri-Fuel Home Backup Portable Generator

It lists a 9.5-gallon tank and up to 19 hours, a runtime figure the DuroMax and DuroStar listings do not quote. It sits below the 20,000-watt Westinghouse in size and price.

It suits base-camp operators who want long runs between refuels. It also works as transfer-switch-ready home backup.

Key dimensions & specs

  • 11,500W gas, 10,500W propane
  • 550cc, 9.5 gal tank
  • Up to 19 hours

Pros

  • Up to 19 hours per tank
  • 11,500 running watts on gasoline
  • Remote electric start
  • Three-year limited warranty

Cons

  • No CO sensor named in the listing

The Catch

The listing names no CO shutdown, so keep the unit well clear of living spaces.

Best Feature Pack· 5 of 6

GENMAX 15000W Tri-Fuel Portable Generator

Danny’s Take

A feature-heavy 15,000-watt unit with a CO sensor and a big tank.

Best for

Feature-rich large rigs
Check price on Amazon for GENMAX 15000W Tri-Fuel Portable Generator (opens in a new tab)
GENMAX 15000W Tri-Fuel Portable Generator

Why it made the shortlist

The GENMAX 15000 provides 11,000 rated and 15,000 peak watts with a 10.56-gallon tank, a CO sensor, ATS and a digital display. A 50A output, a DC cigarette lighter outlet, an LED rope light and a 3-year warranty with lifetime technical support are listed.

It lists the biggest tank of the mid-size units and a higher peak than the Westinghouse 14500 Tri, with a CO sensor and ATS named.

It suits large-rig owners who want an automatic transfer option and a digital readout. The rope light helps at a dark camp.

Key dimensions & specs

  • 11,000W rated, 15,000W peak
  • 10.56 gal tank, 50A
  • CO sensor, ATS, display

Pros

  • Biggest tank of the mid-size units
  • CO sensor and digital display
  • ATS option for home backup
  • Lifetime technical support

Cons

  • Heavy for campsite use

The Catch

A generator this big is a fixed camp or home machine, not a carry-in item.

Best for Extreme Power· 6 of 6

Westinghouse 28000 Peak Watt Tri-Fuel Home Backup Portable Generator

Danny’s Take

The largest option, for event camps running several big rigs.

Best for

Event and ranch camps
Check price on Amazon for Westinghouse 28000 Peak Watt Tri-Fuel Home Backup Portable Generator (opens in a new tab)
Westinghouse 28000 Peak Watt Tri-Fuel Home Backup Portable Generator

Why it made the shortlist

The Westinghouse 28000 produces 20,000 running and 28,000 peak watts on gasoline, 18,000 on propane and 16,000 on natural gas, using a 999cc V-Twin engine. It has two 50A outlets, two 30A L14-30R outlets and a 125A terminal block for hardwiring.

The Westinghouse 14500 Tri and the 13,000-watt units sit well below it.

It suits event organizers and farm or ranch camps running multiple rigs. It is also a whole-home standby option with an electrician.

Key dimensions & specs

  • 20,000W running, 999cc V-Twin
  • Two 50A, two 30A outlets
  • 125A terminal block

Pros

  • 20,000 running watts, far above rivals
  • Two 50A outlets for big rigs
  • 125A hardwire terminal block
  • Remote electric start

Cons

  • Most expensive unit here
  • Far too big for a normal campsite

The Catch

At this size, a generator needs a licensed electrician for hardwiring and a dedicated spot.

How We Built This Shortlist

Each pick was assessed across 5 criteria weighted for real-world use.

Output per fuel
Gas, propane and natural gas running watts were compared across the six units.
Outlets
We checked each listing for 50A and 30A outlets that match large RV inlets.
Fuel capacity
Tank size and quoted runtime were weighed.
Safety
CO shutdown and automatic shutoff features were checked.
Fit for camping
Weight, size and price were weighed against site use.

What Matters Before You Choose a Tri Fuel Portable Generator For Camping

Key buying criteria so you get the right fit the first time.

  1. Fuel-specific output

    Propane and natural gas output is lower than gasoline on the same engine, so a unit marked 11,500 gasoline watts may only give 9,500 on natural gas. Plan against the lowest figure for the fuel you will use. The listing names each fuel's figure.

  2. Starting surge

    A big rooftop air conditioner draws a surge when it starts. Peak watts cover that surge, while rated watts are what you run all day. Use rated watts to size your loads.

  3. Outlet panel

    A large motorhome uses a 50A inlet, and a generator with a 50A outlet plugs in directly. A 30A trailer needs a TT-30R or an adapter. Read the outlet list on the listing.

  4. Carbon monoxide protection

    A CO shutdown sensor can reduce the risk from a faulty exhaust path but does not replace placement away from sleeping areas. Large generators put out a lot of exhaust. Always run them outdoors and far from vents.

  5. Weight and campsite fit

    Generators in this class are heavy and loud, and most campgrounds will not allow them. Use them at dispersed sites, event camps or home. The listings rarely give weights, so measure your vehicle space.

Natural Gas vs Portable Fuel

Natural gas
Natural gas gives near-unlimited runtime on units like the Generac 12500 Tri-Fuel when you have a gas line, which suits home backup rather than campsites.
Gas and propane
Gasoline and propane work anywhere you can carry fuel, making them the useful modes for the Generac 12500 Tri-Fuel and Westinghouse 14500 Tri.

Most campers should plan around propane and gasoline on the Westinghouse 14500 Tri or similar, and treat natural gas as a home bonus.

In this comparison
The GENMAX GM15000ET and DuroMax XP13000HXT list 50A output, and the Generac 12500 Tri-Fuel adds COsense.

When to Spend More

Spend more if
Spend more on the Westinghouse 28000 Tri if you run several rigs or an event camp, since no other unit offers its output or 125A terminal block. The GENMAX GM15000ET is a step up for features and a CO sensor.
Save if
Save with the DuroStar DS13000MXT, which gives tri fuel and 13,000 watts at the lowest price. The Generac 12500 Tri-Fuel is a modest step up for safety features.

Before You Bring One Home

Are tri fuel generators good for camping?

They suit large RVs and base camps more than tent sites, since they are big and loud. For a small trailer, a dual fuel inverter is a better fit. Tri fuel shines when the same unit backs up a home.

Can I run a tri fuel generator on natural gas at a campsite?

Only if the site provides a gas line and you have the right hose and regulator. Most campsites do not, so gasoline and propane are the practical modes. Check the listing for the natural gas output figure.

Which tri fuel generator has the best runtime?

The Westinghouse 14500 Tri quotes up to 19 hours on a 9.5-gallon tank. The Generac 12500 Tri-Fuel quotes 14 hours at 25% load. Runtime depends on the load, so check the percentage in the listing.

How do I switch fuels safely?

Shut the engine down, turn the fuel selector and connect the right hose. Never switch fuels while the engine is hot or running unless the manual allows it. Follow the manufacturer's guidance.

Do I need an electrician to use a big generator at home?

A transfer switch or hardwire connection needs a licensed electrician. Never backfeed a house through a dryer outlet. Portable use through outlets does not need one.

Bottom Line

Best overall: DuroStar DS13000MXT 13 — best value tri fuel pick in this roundup. See the full verdicts above for every pick, with pros, cons and who each one suits.
