One way or another, there is too much stress on the tie downs.
This predicament seems like one or more of three things is happening:
1. Tie-downs too tight. Yes, I've been there and had to pull the first layer of siding off to assess the problem. The problem was dry rot on the bottom 1x2 wood framing, and tie-downs too tight. It's just so counter-intuitive. Loosen to save the TC framing?
2. The surface the camper is on is not flat or too slippery and allows the camper to skate to one side or the other. A good, sticky, thin bed matt will give you more friction and resist skating.
3. You don't have camper guides or some way to 'keyway' the bottom of the box to keep it from moving. Don't underrate this woe. Just moving an inch or two to one side loosens one side of the tie-downs but verily tightens the other side. I have seen this over and over again. It's just so counter-intuitive.
