I have a BD3 and it is very robust. The 18K rating is adequate for most fifth wheels, I would think. At least it is for us. I do wish the 3500 pound pin weight rating was higher but, again, it is probably adequate for most. I would like the extra capacity of the TS3 but I have no way to remove it. My wife and I can handle getting the BD3 in and out by ourselves. I only did one test run with our 2012 GMC 3500 srw, which I just sold, and there was a marked improvement in the chucking we were getting. I think the new dually and this hitch will be a good combination.
