2019 Forest River Surveyor

I have had to replace my tires with less than 5K on them because the leaf spring on the right rear of my RV trailer has flattened out and caused my tires to rub the underside of the camper causing smoke. This appears to be a common problem with my RV trailer (2019 Forest River Surveyor), and the company has told me this is a critical component and will not give me any information about part replacement. I have been advised by my warranty company not to try to pull this until it fixed due to the hazard it would cause if the spring broke. Meanwhile I have 20K Camper that I can't even put on the highway. I think they should recall these junk springs and replace them

Brake drum assembly and wheel fell off my RV on a smooth highway because Lippert did not install a locking cotter pin. Lippert denied the warranty claim, stating it was a bearing failure. Further, the shower drain and outdoor kitchen drains were broken and Forest River has a recall on them. The tires on the 2019 we dated 012018 and all blew out in 2021. The tires are 6-lug but the spare was a 5-lug. Having blowouts and a losing a wheel at 60mph could have seriously injured or killed someone. How is that this level of crap quality is allowed?!? Lippert denied the warranty claim stating that it was bearing failure. How does a bearing failure cause a wheel and brake drum assemble to fall off? There is not bluing on the shaft so I don't see how they can claim a bearing failure. This repair cost me over $2,000
