Service for a rig used in New Hampshire
Know the exact length and height with everything fitted, because the limits here are published in inches. Covered Bridge Campground gates at seven foot nine, the Auto Road at a 176 inch wheelbase and 93 inches of width, and the state park system caps a site at four adults and six people.
Hookups are thin. Dolly Copp charges 14 dollars a night for electric on top of 30 for the site, Lake Francis has nine sites with water and 20 amp power, and Umbagog splits 27 developed sites from 33 that only a boat reaches. Winterising matters because the season on gravel is short at both ends.
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 New Hampshire?
From Conway at 461 feet to Mount Washington at 6,288.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
