December tips for New Hampshire
Nights dip to freezing or below: insulated water hose, tank protection or a winterized rig, and extra propane.
Carry traction boards and check chain requirements before any mountain route.
Plan shorter driving days — winter-pattern daylight is limited and campground offices close early.
