Keeping a camper working through the cold
A camper in North Dakota lives with a long, hard winter and a short shoulder season. Snowfall averages 30 to 55 inches and the state expects blizzard conditions most years, so ask a service centre how they would protect plumbing, tanks and batteries against hard freezes and how they seal a roof against wind-driven snow.
Size matters on the dirt. The grassland roads and the gravel into the Elkhorn Ranch Unit are not built for a long rig, and a big camper on wet clay is difficult to turn around, which is the point at which most trips here go wrong.
A camper van, truck camper or expedition vehicle has two sets of systems, and most mechanics only want one of them. RV and van service centers work on the living side: the 12-volt system, heat, water, ventilation and everything that leaks or rattles loose after a season of dirt roads.
Typical work
01House battery, charging, solar and inverter diagnosis
02Diesel and propane heaters, and water heaters
03Plumbing, pumps, tanks and winterizing
04Roof fans, air conditioning, windows and seals
05Appliance service and leak repair
How to choose a service center
These systems are brand-specific, and so is the training.
01Ask which brands of heater, battery and inverter they are trained on.
02Ask if they will work on owner-built or small-builder vans. Some will not touch wiring they did not install.
03Ask about turnaround in season. Service backs up in spring and summer.
04Bring documentation: a wiring diagram, a component list and photos from the build.
What to have ready before you ask for a quote
Model numbers save a phone call.
01The vehicle or camper, and who built it
02The components: battery type and size, inverter, heater model
03What it is doing, and when
04Photos of the installation
05Where and when you can drop it off
Questions people ask
My heater stopped working at altitude. Is it broken?
Maybe not. Fuel-burning heaters can struggle at high elevation and may need an altitude setting or kit, and they soot up if they only ever run on low. A service center that knows the brand can check it and set it up for where you camp.
Can a shop add solar or lithium to an existing system?
Usually, but lithium batteries need compatible charging from the alternator, solar and shore power. A shop should look at the whole system rather than swap the battery and hope.
How do I winterize a van?
Drain or protect anything that holds water: tanks, pump, lines, water heater and filters. How you do that depends on how the system was built, so ask the builder or a service center to show you once.
How high is North Dakota?
From Walhalla at 981 feet to White Butte at 3,506.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
