Restoration Camping Trailer Design & Build

From Salish Sea Wiki



The Ecosystem Guild has been prototyping restoration camping trailers to suppport the Skykomish Bio-Cultural Restoration Field Station since 2022. The aim has been to develop a easy to construct trailer that can support dispersed camping for a group of 10-20 that will support the Guild Vision (see Cereghino 2023 Ecosystem Guild Handbook.)

Design Citeria

  1. Waterproof on the freeway at 6o mph - this requires that all seams and surfaces are sealed, and doors are gasketed and under uniform pressure (an appropriate hinge and latch system that evenly compresses the gasket.).
  2. Can be pulled by small utility vehicle - Total weight loaded of less than 2000# to easily hit the towing capacity of most 4-cylider small SUVs.
  3. Easy to dry out This means that after camp, aftern packing, and being parked outside a tarp and simple electric heater inside the trailer can dry it out and keep it from mildew. This likely means design for the easy through-flow of air, such as gaps, permeable panels, and thermal flow pathways (while still meeting criteria 4). This likly includes isolation of very wet elements (tarps and ropes) that must be removed and dried before storage.
  4. Least cost, rapid construction with easy to acquire materials - This likely means painted wood, likely cedar frame with a painted exterior plywood skin of minimum thickness.
  5. Easy to repair - Exposed fasteners, minimal gluing, and simple trim details allow panels to be removed to access framing.
  6. Maximum adaptability over time - focus on the initial build is on a good shell, with internal details that can be adapted. The internal framing should be minimial while supporting a variety of internal compartments while meeting criteria 3.
  7. Provides foundation for rapidly assembled shelter - the trailier arrives first on site, and easily establishes a base of operation in bad weather in winter.
