Best thing, which we have done a few times on past rigs, is just change out everything, supports, bumper, etc. I usually change out the box tubing coming from the frame rails and go back with a way thicker 4" square tubing on the bumper. At least I know what I have then. The stock bumper is too thin for much more than a sewer hose holder. I don't even like a spare tire on it. In addition to that, I fab and weld on my own receiver hitches. The Jayco already had one, but it too has been reinforced since the frame mounts only had 3 stitch welds holding them on.
To each their own, but I don't trust anything chassis wise from LCI. I usually always find myself redoing welds or adding more. I don't care if it does void warranty.
