Re: ARRRGGHH! Trailer help please
Trailers can get into uncontrollable oscillations if the weight goes or shifts too far back, and can turn over your tow vehicle or take you into oncoming traffic, so I recommend that you be properly armed with knowledge if you decide to mess with the cg location. Don't trust your registration papers, get it weighed at a local truck scale like djohns says. You can get your all up weight(tow/trailer/boat) and boat axle weight for less than 10.00 in these parts, and if inconvenient to unhook the trailer, measure the tounge weight later with a bathroom scale and add that to the trailer axle wt to get the total boat/trailer wt. When I bought my boat the single axle trailer had automobile tires that were overloaded by some 50%. I had to have those weights to figure that out.
