John E Davies Posted November 29, 2018 Share Posted November 29, 2018 Looking for input. I have the front cargo tray and twin 30 bottles. With full propane the tongue weight is 720 lbs with a full load of gas and water in jerry cans. This is using a Shurline 1000 pound tongue scale. I use an Andersen and 10 or 12 psi in the rear airbags. No worries. If I build a rear frame mounted cargo rack like the factory units, bolt my Ollie cargo tray to it and carry the full cans back there, the tongue weight should drop significantly. Say the rack weighs 20 pounds, the tray weighs 16 - I would remove 116 from the front and add 136 to the rear. Can someone tell me how much the ball weight would drop to, maybe 550? Have those of you who carry heavy ebikes or other stuff in back actually weighed your trailers tongues with a scale? I am trying to figure out what a safe minimum weight would be. If I can drop it significantly I might be able to eliminate the Andersen and pump my bags up to compensate. And use an offroad coupler. My truck is rated at 850 max tongue, dead weight. But it moves around too much the way it is now with the chains disconnected. Note I haven’t weighed the axles. I think the trailer weight is normally 6000 pounds with no extra fluids up front, so my current tongue weight is about 10%. I guess I could remove the tray this winter, shift it and the cans to the top of the rear bumper and weigh the tongue to see what happens, but I was hoping for an easy answer.... there is probably a formula involved. Thanks for any comments.
