Hundreds if not thousands of folks have done the CHF on there F53 chassis. I have yet to read of anyone trashing the frame. I would think the end link would break long before there was an issue with the frame. There are literally a half a bazillion YOU TUBE videos on the same modification and a bazillion posts on the MH forums.
I did the front and rear CHF on my ACE 27.2 today. In my case the front was more difficult than the rear. My next move before we take an extended 4 week trip through the Rockies is to put a Roadmaster steering stabilizer on the coach and a rear track bar.
