When my buddy and I started we guessed it would be $4,000 each and take a summer of the weekends and the odd weekday evening to build two trailers.
Here we are at $10,000 each and 18 calendar months, we have one trailer completed as an empty shell and the second with walls up but not skinned.
We can now see the light at the end of the tunnel and have no regrets.
For encouragement, consider this. As we neared completion every piece we added made the trailer suddenly much stronger and much prettier, so our weak and ugly ducklings took a dramatic improvement at the end into strong and beautiful little trailers. You will likely find the same for yours.
