Pardon my ignorance on this subject but I am not a machinist or metal guy

Welding shop called me today after getting my trailer that was rear ended couple weeks ago

Working up estimate for other driver insurance company and told me the trailer is over 1” out of square , maybe little more

I understand if out of square it can wear tires quicker, tandem axle trailer (16’ ) . Metal shop said tandem axle trailers worse than single axle trailer if out of square

How big a deal is this , trailer was fine before it was hit but I am sure State Farm will only pay me ACV of trailer which means it gonna cost me to replace it. I am fine with that if I need to do this

Shop’s estimate may be more than they want to pay to fix anyway just like to have all the information before I deal with them on settlement or repairs
