Big-Rig-Friendly Campgrounds in Montana
This guide ranks eight Montana campgrounds verified to accommodate 40-foot and larger motorhomes, based on actual site dimensions in the CampIntel database. Each listing includes site count, hookup availability, modeled cell coverage from FCC data, and a CampIntel Score reflecting overall campground conditions. Only one of these campgrounds (Woodbine) shows any hookups in our data, and that's limited to 30-amp electric — plan accordingly for water, waste, and additional power needs. Use this data to match your rig size and connectivity requirements to real capacity.

What the Hookup Picture Tells You
Only one campground on this list—Woodbine, with 35 sites and a score of 61—offers any hookups at all, and that's limited to 30-amp electric service. The remaining seven campgrounds provide no hookups whatsoever, meaning big-rig campers will need to rely on their onboard tanks and generators or external power solutions. If 30-amp hookups are essential to your trip, Woodbine is your only option here; otherwise, expect a dry-camping experience across all other sites.
Cell Coverage and Your Connectivity Options
T-Mobile modeled coverage is estimated at strong levels at Devil's Elbow (43 sites, score 78) and usable levels at both White Sandy (30 sites, score 79) and Rexford Bench (24 sites, score 57), based on FCC National Broadband Map data. Five of the eight campgrounds show no modeled cell coverage, meaning you should not rely on cellular data at those locations. If staying connected is a priority, Devil's Elbow and White Sandy rank highest on both coverage and CampIntel Score, though signal quality depends on terrain and distance from towers.
