bought a trailer down in miami and she is approx 29" too short for my boat (hangs off of bunks). I want to extend the tongue by about 3 ft. The current coupler is welded to the tongue.... SO here comes the dilema... The current length fits into my garage perfectly. Ideally Id like to keep it that way.... Is it possible to have/make either a break away or swing trailer that is several feet long? Can this be done through just bolts or am I going to need to have it welded?
