KRAIG - The stuff I've ordered from there they've had in stock, like a carb rebuild kit, various gaskets, points/condenser. Shipped same or next day depending on when I call them.
When I used to ask about Onan parts at my local CC dealer the parts guy would laugh. Depending on what and how soon I need the parts, I have had good luck getting them from ANOTHER large dealership that handles off-topic equipment... same brand your Brother sells. They've had to order them, but if I call early, the parts are there the next afternoon, or the second day if I call too late. The reason why I use them, the last Onan brand oil filter I bought at my CC dealer was over $20, I think $22. I get the O/T filters for $8 including TAX. A new oil pan drain plug was NLA from CC, that dealer ordered me a new drain plug for $3.25, and the nylon washer was $3.50, washer was too high priced, but the drain plug was unbelievably cheap IMO.
