What should the tounge weight be on a trailer?<br /><br />For example. I'm buying a 26 ft boat, but the trailer is made for a sherman tank! It's a tandem axle Caulkins.<br /><br />How much should the tongue weight be so I don't crush my truck's axle? Where should the boat sit in relation to the tounge weight?<br /><br />I've towed 19 to 32 ft travel trailers before, and they were both quite heavy. I didn't have any problems both pulling and stopping, however they also had electric brakes.<br /><br />Thanks,<br /><br />H.
