I have a 1990 Chevy 3500 Dually, 454 big block, 1 ton truck. The door sticker is gone, so I cannot see what the towing capacity is. I have tried looking around online, and the best figure I have come up with so far is around 9000, does that sound accurate? I am trying to figure if I can safely tow this trailer I am considering purchasing. The trailer is a 3h slant load stock type gooseneck, with a small tack area in the front (no LQ or anything like that). I believe it is a '95 model Colt. Not sure of the exact weight, seller said she thought it was around 3500. Fully loaded, with 3 horses, tack, feed, etc that would be around 7-8000 roughly. It will not be fully loaded usually, normally 1-2 horses. Does this sound about right, or am I pushing the limit of my truck too much? Thanks for any input :)
