Gas (most commonly propane / propane-butane) is one of the most practical ways to reduce electricity demands and increase self-sufficiency at events in a catering trailer or food truck. At the same time, it's not worth improvising with gas – proper system design, safe cylinder placement, high-quality components, and regular inspections are essential.
Why deal with gas at all?
At festivals and markets, electricity is often limited, expensive, or unstable. Gas allows you to move high-consumption tasks off the electrical grid (cooking, heating) and leave electricity for cooling, lighting, POS systems, and sensitive appliances. The result is easier “power management” and less stress during operation.
Another benefit is self-sufficiency. If the gas system is well-designed, a smaller generator or just a minimal electrical connection is often sufficient in practice.
When gas in a catering trailer or food truck pays off the most
Gas makes the most sense when:
- you do hot cooking (grill, plancha, fryer, wok, boiling),
- you need stable performance without dealing with an extremely powerful electrical connection,
- you attend events where electricity is limited or expensive,
- you want to reduce peak consumption and minimize the risk of tripping circuit breakers.
Conversely, for concepts dominated by cooling, ice, and coffee machines (café, bar), gas may be an optional extra or not needed at all – the core will be high-quality electricity and a smart circuit layout.
Most common gas appliances in mobile operations
In a catering trailer or food truck, gas is most commonly used for:
- grills and planchas,
- gas fryers,
- stoves and wok burners,
- selected heating elements depending on the concept type.
The choice of appliances should always be based on the menu and workflow, not the other way around. When the concept is set up correctly, gas can significantly simplify both operation and logistics.
Cylinder placement: why an external box outside the interior is better
In mobile operations, it is a common and practical choice to keep gas cylinders outside the interior in a separate, ventilated space. At Gastronova, we solve this with an external box on the drawbar outside the interior, typically for two 10 kg cylinders. Such a solution is safe, practical for cylinder replacement, and helps keep the interior clean without unnecessary risks.
Regulation and components: what is important
The goal of regulation is to have a stable and safe gas supply to the appliances while allowing for practical operation at events. Therefore, a two-cylinder regulator is often used, which can simplify operation when replacing or switching between cylinders.
In our setups, we use high-quality gas lines, and in practice, stainless steel braided gas flexi hoses with fire resistance up to 650°C have proven effective.
In an external box for two 10 kg cylinders, we typically install a two-cylinder regulator, for example:
Safety in practice: what not to underestimate
With gas, it is crucial to minimize the risk of leakage and have clear operational habits:
- regularly check connections, the condition of hoses, and regulation,
- have a procedure in place for situations where gas can be smelled,
- ensure proper ventilation and safe placement of cylinders away from heat sources,
- use only suitable components intended for the specific application.
Propane-butane is heavier than air, so it can settle near the floor in the event of a leak. This is also why good ventilation and the sensible placement of safety features are prioritized in practice.
Gas vs. electricity: an easy decision for your concept
If you are deciding whether to include gas in your concept, this simple process will help:
- List your top appliances that will be running during peak hours.
- If heating appliances dominate (fryer, grill, oven, water heating), gas is often the most practical way to reduce electricity demands.
- If cooling, ice, and the coffee machine dominate, electricity will be the core and gas may be an optional extra or not needed at all.
How we handle gas at Gastronova
We always design the gas system in a gastro trailer or food truck as part of the overall concept, ensuring it makes sense alongside electricity, facilities, and hygiene. Our gas distributions are professionally designed and subsequently inspected—we deliver trailers with a completed gas system revision.

Final recommendation
If you have high electrical consumption in your trailer or want to be independent of event electricity, gas is often the most practical step. It works best when the system is designed according to the concept and appliances, stored safely (ideally outside the interior in an external box), built from high-quality components, and regularly inspected. In that case, gas increases operational stability, reduces stress, and gives you more options for where and how you can sell.
FAQ – Gas in a catering trailer or food truck (frequently asked questions)
1) When is gas in a catering trailer or food truck really worth it?
Especially when you have high electrical consumption in your operation (fryer, grill, oven, water heating) or attend events where electricity is limited or expensive. Gas will reduce kW peaks and increase self-sufficiency.
2) Is gas safe in a mobile operation?
Yes, if the system is correctly designed, professionally installed, regularly inspected, and cylinders are stored outside the interior in a ventilated space. The greatest risk arises from improvisations, low-quality components, or neglected inspections.
3) Why is it better to have gas cylinders in an external box outside the interior?
An external box is both practical and safety-conscious: cylinders are outside the workspace, they are easier to replace, the risk inside the interior is reduced, and the entire solution is clearer for event operations.
4) How many gas cylinders are commonly used?
In practice, a common solution is two 10 kg cylinders, so that you have a reserve and don't have to deal with replacement during the biggest peak. The specific need depends on the appliances and the intensity of cooking.
5) What is a two-cylinder regulator good for?
It simplifies operation and increases comfort – with two cylinders, you can ensure smoother operation and plan replacements better. It is particularly practical for longer events or for appliances with higher consumption.
6) What appliances are most commonly connected to gas in a catering trailer or food truck?
Most commonly a grill/plancha, gas fryer, stove, or wok. Gas is worth it wherever electricity would create extreme peaks or where you would have to deal with very powerful connections because of it.
7) How do I know whether to use gas or electricity for my concept?
Look at your “TOP appliances at peak times”. If heating dominates (fryer, grill, oven, water heating), gas is often the best step. If cooling, ice, and coffee machines dominate, the core will be electricity and gas may be an extra or not necessary at all.
8) What is the most common mistake with gas in a trailer?
Most often, it is underestimating design and maintenance: incorrect cylinder placement, low-quality components, improvised connections, or a lack of system inspection. These are things that can cause a problem at the worst possible moment – at an event.
9) Do I need a revision for gas in a catering trailer or food truck?
For mobile operations, it pays to have the system professionally designed, inspected, and documented. At Gastronova, we handle gas distributions professionally and deliver trailers with a completed gas system revision.
10) How often should gas in a trailer be checked?
It depends on the intensity of use and the type of components, but in practice, it pays to do a regular leak check and visual inspection before events (hoses, connections, regulator) and a professional inspection at intervals according to service recommendations and regulations for the specific type of operation.
