Greenlight is the RV checklist and weight calculator that tells you, before every drive, if your rig is ready to roll.
Pick your rig (travel trailer, 5th wheel, Class A or camper van), copy the numbers from the weight sticker inside your door, and Greenlight does the rest.
READY AT A GLANCE
One screen shows weight, hitch, clearance and checklist. When everything is clear, you get a big green light.
WEIGHT
See your cargo against the Cargo Carrying Capacity and your gross weight against the GVWR, with clear "within limits", "near limit" and "over limit" warnings.
DEPARTURE CHECKLIST
Interior, exterior, hitching and mechanical steps, filtered for your rig type. No slide-out steps for a van, no kingpin steps for a bumper-pull.
GREENLIGHT PRO (one-time purchase, no subscription)
• Itemized loading: fresh, gray and black tanks, gear presets with your measured weights, permanent upgrades like batteries and solar, and passengers for motorhomes
• Tongue and pin weight check: keep 10–15% (trailers) or 15–25% (5th wheels) on the hitch, including the shift as holding tanks fill
• Clearance dashboard: your height, width and length in giant, high-contrast numbers, in feet or meters
• Custom checklist steps and auto-reset 4 or 6 hours after you finish, so a lunch stop never clears your list
