Thanks for the info. This was one of my concerns recently when I was under there to mount a biker bar to secure my Harley. I saw that the metal was thin and quite corroded for only being a few years old. The previous owners only had kennels for their two dogs in the garage. Can you by chance give me a little bit of info on the replacement? This RV thing is new to me. I have some repair skills, mostly limited by lack of proper tools and equipment. The other confusing thing to me is where to get parts and if I'm unable to make repairs myself, who and where to go. From everything I read, the dealerships all take forever to get into and/or they do shoddy work. I do have one place in town that does rv work and I'm going to discuss some of my issues with him shortly. My recent mistake was overfilling my battery and it boiled over. Cleaned everything up, got it to the right levels, hooked it up and plugged it in. It charged up but died shortly thereafter. I'm researching batteries now. Can you tell me specs to look for in shopping for springs and brackets? Again, thanks for the info.
