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.
