I got a weight on the carrier....it's not too bad at 260 lbs but the hitch that I'm planning to build to carry the carrier is another 180 lbs plus the 800 or 850 for the bike and things are starting to get heavy. It could be a total of 1290 lbs....yikes. The likelyhood of adding an axle is growing. With some more accurate numbers it looks like the pin weight will be more like 1300 lbs....it's going to be 1/2 ton towable by the time I'm done with it.
