Any advice out there for a guy who can't seem to get his boat to load evenly onto the keel roller of a roller model trailer, even on a CALM day, with out wind & the trailer evenly in the water? I've had people on the lake tell me everything from "the trailer can only be with the lights in the water"...to "the whole thing has to be submerged!" Neither worked. Could this be an issue of needing to distribute my gear weight on the boat better......or should I just start shopping for a new trailer? It's a 1995 Spartan trailer, just F.Y.I.
