At JCR we hope to start building QUALITY trailers for specialty hauling (4x4's, hot rods, etc...)
After looking for (and building) trailers for ourselves we feel like there is a lot to be desired... even a $2000 new trailer lacks in a lot of areas.
Brian is doing a buildup right now (his second for himself), and if your interested I can keep you updated.
I personally dislike:
Brakes on 1 axle only
Angle iron construction
Decks not screwed down
All of which you can find on a $2000+ trailer
Any other problems you have?
