I purchased a Triad 5700-7900 Lb. model in 1995 for J/30 AEOLUS #085. This trailer is well built and has served very well. Built of 7", 6" and 5" structrual C channel, 1.5" x 1.5" angle iron, schedule 40 pipe. Tandem 5,200# axle: 3" diameter axle tube with 4" drop. Four 12" x 2 1/4" electric brakes with Dico 25,000# coupler. Goodyear Marathon ST225/75R15 tires on white mini-mod "E-Coat wheels. Fulton 2000# front jack with removable swivel caster wheel. Two Bulldog Topwind 2000# rear corner jacks. 5/16" proof coil safety chain. All lights are fully submersible (still lift off only). Eight screw poppet pads. Substantial keel support. 4 tiedown loops. Triad has been building boat trailers for 30 years. Michael Orro will be happy to meet and exceed your needs. A complete web site will show their purducts. AEOLUS photo to follow.
