The thread title more or less says it all. The Wanderer design is a tiny standy (just) to go on a 1720lb Harbor Freight 4x8 trailer with either an 8 foot or 10 foot long body.
Laden weight as designed is only 1300-1400lb but the trailer is 78" wide by 83" high, so it's not an economical tow. But those who only tow 50-100 miles might prefer more comfort at their destination to easy towing.
This was inspired by the Wander Pup and Wander Bug designs in the Vintage Plans, hence the name.
