A Focus on Strength and Durability
We use a superior grade of kiln dried Douglas fir to make our frames stronger, lighter, water resistant, and more durable. A lot of manufacturers save money and use pine, but it won't last as long, especially with only staples to hold it together; we add screws to the frame and bond the interior walls to the frame with pressure cured adhesives to form shear panels. After the frame is completed, we wrap a band of high tensile steel around the body of the camper at the midpoint and then secure the band under tension. This strengthens the frame for even greater durability.
Modern manufacturing has surpassed aluminum and EPDM synthetic rubber as roofing material. We now use a thick one piece sheet of thermoplastic olefin (TPO) on every roof - providing as much as 50% more tear and puncture resistance than EPDM rubber, with less weight, excellent UV protection, and rot resistance. We still use aluminum siding, though. Quite simply, it's lighter, stronger and has a longer life than other materials such as fiberglass. Silicone caulking is wonderful stuff - but we don't use it on any of the exterior weather surfaces. Butyl caulks and urethane sealants maintain long lasting resiliency and waterproofing, and have far superior adhesion - that's why we go the extra mile and dollar to use them exclusively.
Details, Details, DetailsLittle things make the difference, but when it's your camper, there's no such thing as a "little thing." Here are some examples of the attention to detail that goes into building a Six Pac:
