What is the needed part in question? Can a similar part for another year/model genset be made to work by an experienced repair guy? Perhaps a complete same used genset, in working order, could be found, bought and have installed cheaply enough. Spend some time asking around about possibilities and alternatives. If you can find a new Onan LP genset that will fit, and you want to keep your rig, maybe a new genset would only cost two thousand dollars more that trying to fit and install a different type of genset. Some long time genset repair guys have sheds full of used generators that may fit your rig. Also, consider peddling your old rig and buying newer rig with good genset, batteries, converter/charger, etc. A working RV generator can come in handy during power outages or merely to operate the microwave for lunch.
