We started the design process with a few loose guidelines...
- Finished weight less than 1,500 pounds (under 1,000 if possible) for towing with minivan.
Fits in garage (under 7 feet)
Sleeping accommodations for two adults and three kids (ages 2 to 5).
Preferred to keep the width and height small for minimal drag.
Here's the trailer I had to start with. 8X5 flatbed with one foot side rails.
