If towing a trailer a lot, the rolling motion can egg out the ball receiver on the trailer. I like the ones that hook up to the top link as well as the side arms.
No grades in the nightschool version I took. But, it sure was a lot of fun. In fact, I took the course a second time, just because I was having such a great time. Oh, and I learned at least a little about welding, too. A VoTech welding course is highly recommended.
Your setup reminds me of THIS ONE . Does anyone here have one of the Bad River models or does anyone know if this company is still selling them? I don't know when I bookmarked their website, but just rediscovered it and could use one like that.
Thanks,
Terry
