While mileage isn't a totally reliable indicator of brake wear or condition; feel, braking performance, brake stutter or shuddering, and effectiveness or lack thereof at certain speed ranges, is a much better indicator of brake condition, mileage is a good pointer as to if your brakes should be serviced.

Take the VIN to any dealer or parts seller and that will tell them what parts your motorhome should need. Because your vehicle is considered an incomplete vehicle when the VIN is issued, lots of parts aren't going to be searchable by VIN, such as lights, trim, heat and AC, a fair quantity of the electrical system. What the VIN will do is get you to the really big things, like engine, transmission, suspension, brakes, cooling.
