I am visiting family and am away from my '92 Itasca. Last spring we began looking at the built in generator, which runs great, has only 23 hours on it, but is noisy as heck! The muffler on it has all but rusted away.We tried repairing it with various tapes, tubes and what not. It didn't take. So, am now looking to replace it if possible. I will be travelling to Montana this month from BC, Canada, if anyone knows of a US business I might find one at, or here in Canada will work too. It is an Onan, but I couldn't tell you which model without going out to look at it. Thanks for any help you might be able to give.
