Every October I sit down with a legal pad and write out what earned its square foot in the motorhome that year. The Gas One GS-3400P has made the list two years running. We bought it in the summer of 2024, back when Ray and I were still learning that a 25 foot Class C does not have room for everything we assumed it did. It lives in its carry case in the outside storage bay. It comes out four or five nights a week, more in July and August.
I am not a gear reviewer. I am a retired school librarian from Salem, Oregon who cooks three meals a day in a galley the size of a closet, and I have strong opinions about what fits in the one narrow drawer. What follows is not a spec sheet read aloud. It is the list I would hand to a friend who just bought her first rig and asked me, honestly, whether one more cooking appliance was worth the cupboard space.
The third burner that lives in the storage bay and never asks for a match
It runs on butane or a 1 lb propane cylinder, lights with a click, and folds into its own case. Two years of daily use in our rig, and it has never been the thing that failed.

The GS-3400P takes a butane canister on its own, or a 1 lb propane cylinder using the adapter that comes in the box. That reads like a small feature until the afternoon the only store for thirty miles has butane and no propane, or the other way around. I have made that drive. I do not make it anymore. I buy whichever is on the shelf and dinner does not depend on the answer. In cold weather I lean toward propane. In mild weather butane is simpler to seat and lighter to carry from the bay to the table.
8,000 BTUs takes a quart of water to a rolling boil before the coffee finishes dripping
This is not a restaurant range and I would not pretend it is. It is enough to move a quart of water from cold to a hard boil in about the time it takes Ray to walk to the dump station and come back. Pasta for two, the coffee pot, the hot water for dish duty: all of it happens without the long wait that makes people give up on cooking outside. The flame spreads wide enough under a five quart pot to heat the whole bottom instead of licking up one side and leaving a scorch mark.
At 3.1 pounds it never shows up in the weight arithmetic
Our rig has a cargo carrying capacity we watch closely. Cast iron, canned goods and a full water tank add up faster than anyone expects, and I have reorganized that bay more times than I care to admit. The Gas One is the one piece of cooking equipment I never think about at a weigh station. It goes in, it comes out, and it does not cost me a pound I have to make up somewhere else. If you travel in a smaller Class C or a van, that arithmetic is the entire argument.
Piezo ignition means a push and a click, not a hunt for dry matches
The stove lights from a piezo-electric ignition, so there is no matchbook involved. On a windy morning at a state park in eastern Oregon I watched a neighbor burn through six matches trying to get a chimney going. I pushed the knob, heard the click, and had a flame in a couple of seconds. When the ignition has been damp, or the stove has sat in the bay for a month, it sometimes takes a second or third push. That is honest. The third push is still faster than finding dry matches in a drawer.
The heat dial turns down far enough to hold an actual simmer
The adjustable dial runs from a wide open roar down to a flame small enough to keep a pot of chili at a bare tremble. That range is what separates a stove you use for boiling water from one you genuinely cook on. I brown onions on it. I hold a two hour simmer on a pot of beans. I have never once had to slide a pot to a cooler corner because the only setting was high. If you have scorched rice on a one temperature camp stove, you know exactly what I am describing.
It folds to 13.5 by 11 by 4.45 inches, and the case keeps soot off everything else
Set up, the stove measures 13.5 inches long, 11 inches wide and 4.45 inches tall. That footprint sits on a picnic table with room left for the cutting board and two coffee cups. Folded into its case, it slides into the storage bay beside the water hose. The case is the part I did not expect to care about. It keeps grease and soot off everything packed around it, so the awning mat does not come out smelling like last night's burgers.
Cooking outside keeps the rig cool and the bacon smell out of the curtains
In July, cooking inside a 25 foot motorhome turns the whole rig into an oven and leaves the smell of bacon hanging in the curtains for two days. We set the Gas One on the picnic table and the heat goes outdoors where it belongs. The galley stays noticeably cooler. The bedding does not need airing out. Nothing in the coach needs wiping down after breakfast. This was the original reason we bought it, and it is still the reason it comes out first every single morning.
It becomes the third burner on nights when two inside burners are spoken for
Our coach has two burners inside. On a night when rice, a vegetable and a skillet of something all need heat at the same time, two is not enough and I start juggling pots and losing my temper. The Gas One becomes the third burner at the picnic table, and Ray takes the coffee pot out with him. One extra heat source costs a cylinder of fuel and a square foot of table, and it turns a tense meal into an ordinary one. That is worth more than it sounds.
Cleanup is a wipe with a rag, not a sink of the water you are rationing
The grate lifts out and the body wipes down with a damp rag and a drop of dish soap. That is the whole job. In a rig with a 30 gallon fresh tank, every quart of wash water is a quart we are not drinking later, so I count them. A stove that needs a sink of hot water is a stove I would leave at home. This one gets wiped, dries on the table while we eat, and goes back in the case before the dishes are done.
It is the same stove I carried into the house when the power went out in January
When the lines came down in Salem last winter, I walked out to the rig, pulled the Gas One out of the bay, and made soup on the back patio. It weighs three pounds. It stores on a shelf. It carries a one year warranty from Gas One, and it has a longer track record with us than that. When a friend asks what to buy first for a new rig, or for an apartment with bad wiring, this is the box I hand her.
What I'd Skip
Two warnings before you spend anything. First, wind. A flame on an open table in a ten mile an hour breeze will struggle, and there is no built in shield on the Gas One. I cut a strip of aluminum flashing, bent it into a three sided wall, and it cost me nothing but twenty minutes. Second, it is one burner. If you routinely put three dishes in motion at once, this is an addition to your inside cooktop, not a replacement for it. And if you want something that lives outdoors in all weather without being carried in and out, a two burner tabletop is the better shape for you. This one is happiest traveling in its case.
Three pounds, two kinds of fuel, and a flame I can turn down to a tremble. Two years of most nights, and it still lights on the first or second click.
Start with the one piece of cooking gear you will actually use every day
Not the fanciest thing in the storage bay. Just the one that comes out four nights a week and has never been the reason a meal went wrong.
