Service for a rig used in Maine

Size governs where a rig can go, so it is worth knowing the exact length with everything fitted. Maine state parks class their sites from pop-ups at 20 feet through to over 35, and hookups exist at only six parks in the whole system: Aroostook, Camden Hills, Mount Blue, Peaks-Kenny, Rangeley Lake and Sebago Lake.

Winterising is the other job. The season on unpaved roads is short at both ends, bounded by mud in spring and snow from November.

The full guide to overlanding Maine

What an RV and van service center does

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

  1. 01House battery, charging, solar and inverter diagnosis
  2. 02Diesel and propane heaters, and water heaters
  3. 03Plumbing, pumps, tanks and winterizing
  4. 04Roof fans, air conditioning, windows and seals
  5. 05Appliance service and leak repair

How to choose a service center

These systems are brand-specific, and so is the training.

  1. 01Ask which brands of heater, battery and inverter they are trained on.
  2. 02Ask if they will work on owner-built or small-builder vans. Some will not touch wiring they did not install.
  3. 03Ask about turnaround in season. Service backs up in spring and summer.
  4. 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.

  1. 01The vehicle or camper, and who built it
  2. 02The components: battery type and size, inverter, heater model
  3. 03What it is doing, and when
  4. 04Photos of the installation
  5. 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 Maine?

From Bar Harbor at 54 feet to Katahdin, Baxter Peak at 5,268. Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
