Free tools for your build. One expedition a year.
Pick your truck and every tool starts from its factory numbers: tires and gears, angles and clearance, the roof rack and tent, parts to print, and soon the tools and torque specs for your mods.
Plan the build. Load the roof. Print the parts.
Pick your truck once. Every tool starts from its factory tires, gears and angles, and your truck carries from one tool to the next.
Do the math before you buy the parts
Tires, gears, crawl ratio, speedometer, links and your real angles from a tape, all from your truck's factory numbers, adding up on one build sheet.
- A straight call on each answer and the line it's drawn at. Past 8% more brake torque, we'd upgrade.
- A link and a printout for every result, so a forum answer can point at your numbers.
- Your rig on one page, with which tool used each of your numbers and which tools are still waiting on one.
Know what each upgrade does to your truck
Racks, tents, tunes, superchargers, intakes, snorkels and exhausts, each checked against your truck’s factory numbers. See the load against your roof’s rating and what it costs at the pump, and how close the power gets you to pulling like stock on bigger tires and a heavier build.
- Your roof’s rating from the owner’s manual, or the rack maker’s when the manual prints none.
- Each power mod’s maker claim next to independent dyno tests, with its California status.
- What helps most on your truck, from a lighter tent to a tune or a regear, with a Try it button for each.

Tools we make, and the plans for our builds
Builds and trip reports, written down in full
Two rigs, nine days and about 680 miles of Casebier's loop. A lost caliper bolt, a Jeep without 4WD on Foshay Pass and the segment we had to cut.
Heated and ventilated Lexus seats bolt right in. The wiring is the part nobody writes down, so here it is, every pinout included.
A Goose Gear quality drawer system for an Ikea price. Extrusion frame, plywood drawers and a fridge slide that didn't fit the first time.
