Hey all, my wife and I bought our 40' International pusher from a local school auction recently. It's a 2004 with a DT466 and an Allison 3060, 180K miles. Overall an excellent setup for us to convert. We took the seats out and are starting on the floors. Near the front wheel well, noticing some pretty bad rust.
I used a hammer and pry bar to pound on this pretty hard, it did no puncture or seem super thin, but curious what everyone's thoughts are? Of course we'll continue stripping it and see what the whole story is.
Funny enough, the bus is super clean underneath, we live in western WA where there are rarely ever temps low enough to need road salts. But it's also wet in the winter, meaning water inside the bus can get trapped I suppose.
Are there treatments that can stop this in its tracks and allow us to not be concerned about subfloors? Should we add structure? This is our first conversion so I have no frame of reference for how bad it is...
