We have a 2019 22RBS. The water pump sounds like an old Jimmy diesel just bogging down on a mud hole. There are ways to quiet them down, but I haven't bothered. Our trailer is the evil one with the window in the front. Eastern version?
We are at about 6000 miles on ours, including the trip from Indiana to our dealer in Manitoba. We pull it with a 2015 F150 SC 3.5 EB. The trailer weighs 5500+ empty, so it is heavy. I do the driving, and the line, "Don't even know it's back there", doesn't apply. I have a Husky hitch and have it reasonably tuned. I just raised the brackets one notch this morning.
Two years ago, i towed a new 21 RBS trailer home, 90 miles, with no equalizer hitch, on a day with a good side wind.
My next purchase was the Husky.
