First, thank you for the info you have provided. I just ordered a 320G, and will be towing it with a '19 RAM 3500 HO SRW SB. Truck loaded up, I have a 3400 lb payload (cat scale number), and 3680 "payload" on the drive axle. It will be interesting on pin weight, as my current bike is only 450 lbs., which with what you have been saying, I may need to add a fair amount of water to have the trailer be more stable.
Just add, and your posts may have pushed them, but as of a month ago, they are offering an 8K lb axle upgrade with disc brakes, which I did get, thanks to your posts about your weight issues.
Wow, that is interesting. I did make a big deal about it over on the other GD forum. However, when I emailed GD direct about upgrading the axles to 8K lb units, they advised against it. Now I am confused why they would advise against it, and now offer it as an option.
My '21 Ram 3500 HO SRW LB is finally being delivered tomorrow. I fully expect it to tow better than the 2500. I think that much weight was just too much for the 2500 and the Geometry of the coil springs. I can't wait to get it!
