Sigh,.. 5" standard is over $4 foot where I live and $140 to
transport. Is there a resource for construction methods and hitches
and brakes and such? I live in WA state. I think my boat weighs about
4.5 tons. I can arc weld after a fashion. I have two free trailer
axles with electric brakes. Thanks and keep up with the grinding and
sanding and painting and epoxying and lofting and wiring and powering
and such.
