Wondering if I could go t a beefier spring and that would help?

I believe I see part or all of your problem.

In the 2 pictures above, I see horizontal rust lines above the spring hangers. This is a tell tail sign of a cracked camper frame from excess flexing of the lower flange of the main frame. If you cannot see them, later tonight I will copy your pic and circle them. Then go check it out on the camper.

Your spring hangers have no gussets to stiffen up the lower flange from flexing and there are no left to right braces between the hangers. A double wammy for frame flex. As you turn the lower flange of the I shaped main rail flexes and the entire axle shifts allowing the tire to rub. You have very little clearance to begin with, problem 1, and then the flange flex does the rest.

This is especially prevalent on toy haulers as those who have toy haulers often go off road to get to the camp site. That off road higher degree of up's and over causes extra flexing of the hanger and rips up the main frame rails. Many toy hauler guys add extra reinforcing from day 1 to offset this problem.

Your prior reply on tire size leads us to believe you bought this camper used. The frame may have been cracked from the prior owner and they may not have known about it either.

I will post later tonight how I fixed my flexing hangers. I would not change springs or even an axle flip until this issue of the hanger flex/ possible frame crack is addressed. After fixing the flex, then have at it if needed.

Hope this helps

PS Take some pics of the inside of the frame so we can see left to right how the frame by the spring hangers is built.

Im interested in how you fixed the flexing. If you could point me in the right direction as far as what I need. A good buddy of mine is a fabricator and master welder and assures me he could weld me in some bracing if need be. Thanks
