Winterizing Your Food Trucks, Trailers and Other Mobile Vessels -a quick guide

It’s been a good while since we’ve posted to the ole blog, and for that we apologize, but life has been busy, and certain things fell off the radar  -I think we can all attest that it has been a whirlwind of events these last couple years causing us all to kind of reprioritize some things. 

All in all, life moves forward and we can only continue to do our best and put the best of what we’ve got out there!

As I sit here trying to figure out what *goods* we could put out there for a) a handy resource and b) SEO - which is annoying, but if we want to do this work we have to go along with it! It dawned on us that winter is just about here and we all could use a good (and quick!)  refresher on winterization for food trucks, trailers and other mobile businesses, because remember

After sitting down with Mike, who has a ton of field experience working and repairing in the snow, he immediately rattled off these important tips to help maintain your rig during the cold season.


  1. Space heater WITH a fan -Aiming the fan towards the interior plumbing allows for that warm air to circulate and prevent the plumbing from freezing. Make sure the space heater is plugged into its own dedicated circuit. Space heaters themselves run on high amperage, so if it is plugged into the same circuit as a fridge or freezer, which is also a bit high, then you have the potential for a breaker to pop. If it is plugged on the same circuit as your fridge/freezer you have the potential to lose your cool inventory once that breaker pops.


  2. Heated supply hose -This is a must if you live in a cold climate. The heated supply hose with ensure you don’t go without water!


  3. Insulation and heat tape  -great product to have and use for any external/exposed plumbing supply lines/drains.


  4. Spigot foam grommet -Most actually throw this out when they get their hose, but keeping it on hand for those winter months or serious cold spells is a life saver. They simply cover the spigot where the supply hose is connected to reduce freeze potential.


  5. Lower hood fan speed -by lowering the fan speed on the hood it helps reduce heat loss inside the vessel, but still blows out smoke combustion and allows for ventilation.


  6. Drains -While parked or If parked permanently always keep an eye on maintaining drains around you if heavy rain/snow -keep area clear and flowing so there is no chance for flooding.


  7. Snow removal -Carefully remove snow from the roof as needed. Since there are fan covers for make-up air fans, there is a potential to break one. Keep snow pulled away from truck to allow for drains and hoses to operate.


  8. Most importantly, if it is necessary -save the money in the winter and do what you can. During these cold months equipment tends to operate a little bit easier -there’s not so much wear and tear vs. in the warm busy season. Come spring it’s important to have equipment maintenance/fixes on the radar and done come summer. 




Let’s not overestimate the importance of some good old fashioned winter preparedness! Following the simple tips from Mike above will most definitely save you a lot of time, money and headaches in the long run. If you are a seasoned winter mobile vessel operator then check out our blog post on tips to keeping your food truck afloat during the winter months.
