Hello
I just bought aa 2016 Winnebago Forza diesel 38 ft. Driving it home on the highway I started to hear a rattle noise from the driver side in the front i don t know exactly from where it was. I brought it to my local camping world . After having it almost a month, They said they found the problem but they did not fix it. Did anybody experienced this rattle noise? It is very aggravating.
