For my very heavy 252G, I had a 2006 Road King that did very well for over 12+ years, but corrosion started to take over. I went back to Road King but overbuilt with heavier bunk brackets, all SS hardware, All SS Road King brakes and 16" custom wheels to get the trailer higher for my case to clear dragging in the driveway.
I priced both Loadmaster and Roadking and they were about the same. However, I had a hard time with the Loadmaster dealer trying to convince me to take what he had in stock I think was the issue. He didn't want to agree I needed a heavier trailer. However, I am very happy with this new Road King and I paid about $9K. If I recall, the Loadmaster was about $7900 without full SS Kodiak's and 16" wheels, so it might have been a bit higher if I could have convinced the dealer what I wanted.
I also have coated the entire trailer with Shark Hyde to protect better from corrosion!
After a year of saltwater dunking, the Kodiak's look like they were just put on the trailer.
