Confused

[Montana_440]

After readin the thread on frame problems,I know less than when I started.Some posts mention stripped screws....others say broken welds cause the sidewall cracks.The Keystone rep told husband it had nothing to do with welds.Some ppl said to be sure & have under hang removed & checked,others say it's a matter of a small sidewall repair.I copied some of the posts...but wether the repair ppl will read it...or care,who knows?
