The only tool built specifically for Tune M1 truck camper owners. Search community-verified gear weights, calculate real payload capacity, and share your rig — before you ever load the truck.
Every feature was designed around one question: can my truck handle this build?
Real-time gauge with color-coded warnings. Covers every weight category — build, water, passengers, gear — against your actual door sticker rating.
Search thousands of scale-verified gear weights. Add your own. Flag bad data. Every weight averaged across real submissions, not manufacturer claims.
Top-down visual of your truck bed as you build. See where cabinets, water tanks, fridges, and recovery gear actually sit.
Water kills Tacoma builds. 40 gallons = 334 lbs. Input gallons and see the real number — empty vs. full tanks side by side.
One link shares your entire build config — truck, gear, water, passengers. Post it to forums, DM it to a friend, or compare rigs side by side.
Pre-loaded payload ratings for Tacoma, Tundra, F-150, Silverado, RAM, Colorado, Ranger, and Frontier. Or enter your exact door sticker number.
No account needed to start. Just open the builder and go.
Select your make and model to load the actual door sticker payload rating — or enter a custom number.
Search the community database for scale-verified weights. Can't find it? Add it yourself — it helps everyone.
Input water gallons and passenger count. See the real payload hit — full tanks are the silent payload killer.
Save your build, get a shareable link, and post it to the community. Sign in with Google or Apple to save permanently.
This tool exists because the M1 community needed it — not because there's money in it. It will always be free to use. No premium tier. No feature gating. No advertisers telling us to push products. No trackers following you around the internet. Just a tool, built by someone who overlanders, for people who do the same.
These are factory-rated maximums. Your actual door sticker will vary by trim, options, and accessories. Always verify before loading.
Sign in to save builds, submit verified weights, and get a permanent shareable link. Or just jump straight into the builder — no account needed.
This tool is free and always will be. But hosting, domains, and the occasional cold brew cost something. If this saved you from a blown suspension or an overloaded rig, consider tossing a few bucks toward the next cup. Zero pressure, zero tracking.
