Anyone gone from Class A to 5er toy hauler or visa versa?

Check this site. automated safety hitch.com I have one it works great with my 3/4 ton single wheel duramax short bed pick up with a flat cover over the bed. Started with a 3/4 ton suburban pulling a 12000 lb 310 fuzion worked great then went to the duramax for more pulling power two years into this and love it. You will hear all the negatives but these people don't own one I do so check out the site.
