Reaching Decker requires traveling State Highway 314 south from Interstate 94, with the nearest I-94 access being Exit 126 near Glendive, about 45 miles north. The route involves two-lane rural highways that accommodate RVs well, though you'll want to watch for occasional farm equipment during harvest season. No significant bridge restrictions or weight limits affect RV travel to the area, but winter conditions can make these rural roads challenging between December and March. The highway department maintains roads reasonably well, though snow removal priorities favor main arteries first. For overnight parking, your options are limited -- Tongue River Reservoir State Park offers the only developed camping in the immediate area. Some RVers dry camp along public access roads near the reservoir, but this requires self-sufficiency since services are minimal. The nearest fuel and supplies are back toward Glendive or south into Wyoming, so plan accordingly. Cell service can be spotty in this rural area, making GPS navigation potentially unreliable once you leave the main highway corridors.
