What this site is
S'more's Outdoors builds small, free, browser-based tools for people who camp out of their rigs — RVers, van lifers, truck campers, and weekend car campers. Every tool runs entirely in your browser: no account, no signup, no app to install, and nothing you type is sent to a server. Enter your numbers, get your answer, get back outside.
The tools
- RV Leveling Block Calculator — match two bubble levels and get exact blocks-per-tire for your rig.
- Can I Tow It? — check a truck-and-trailer combination against every weight rating at once, including the payload limit most buyers miss.
- How Long Can We Boondock? — fresh, grey, and black tank duration for your crew and habits.
- Propane Tank Duration Calculator — honest furnace duty-cycle math for cold-weather camping.
- Will It Trip the Breaker? — shore-power load budgeting and generator sizing with real starting watts.
- Camper Power & Climate Planner — size an EcoFlow battery and air-conditioning kit to your camping style, or rank vehicles by their factory power.
Why the tools are free
The site is supported by advertising and by affiliate links to camping gear we'd recommend anyway. As an Amazon Associate, S'more's Outdoors earns from qualifying purchases made through those links — at no extra cost to you. That's the whole business model: useful tools, honest math, and clearly-marked ways the site pays for its hosting.
Our approach to accuracy
Every calculator explains its assumptions in a "how the math works" section, and every output is an estimate — rigs, habits, and hardware vary. Where safety is involved (towing weights, propane, electrical loads), we say so plainly and point you to the physical checks that outrank any calculator: the sticker in your door jamb, a CAT scale, a CO detector, your owner's manual. Each tool's disclaimer spells this out.
