When my son and I did ours this summer, the front ones went into bottom hole of landing legs (or one just above where pad attaches). The rear, had to have a metal shop weld a bar across frame rail to frame rail so we had a place to mount the rear ones to. Sadly. with the a rear bumper, am unable to use the "T" handles, so in their place, we had extra bolts from the kit that fit nicely in same spot so we use them and a 9/16 wrench instead.
I won't say the JT's eliminate all the "wiggle" out of the coach, BUT they do eliminate a vast majority of it! Very happy with them. Now watch, probly get a new coach in a year or so! Oh well.
