I got my weights. Good news is the trailer axles have room to carry the extra 1800 lbs that the bike and carrier would put on them without moving the axles back. Bad news is that after removing 750 lbs from the pin I will only have about 1700 lbs of pin weight....I think that might be too light. Good news is that the rear axle can tolerate 3700 lbs of pin weight.....So moving the axles back 17 inches would make things work out very nice. I'd have 3000 lbs pin weight with the bike and carrier uninstalled and 2300 lbs of pin weight with the bike and carrier loaded. Total weight of trailer with bike would be about 16000 lbs.
