Complaint Review: 5corners RV

I rented an RV from 5corners rv in september. Iv'e driven multi axle and multi wheeled vehicles a lot of years of my life and iv'e rved for a number of years as well plus i own an F350 duelly so i have some idea as to what im doing. Anyone why has driven a duel wheel truck knows that its pretty hard to damage an inside tire without damaging something else. 5corners said i damaged an inside tire and a hubcap but for some reason they so far have refused to provide me with anything for me to see. they are charging me for a new tire and hubcap without showing me the damaged ones. That tire had almost 24000 miles on it, it should have been prorated. I also believe that the truck was still under warranty
