Does anyone know a way to find out what kind of axles I have under my trailer? I dont know what kind a travel trailer it was because when I got it there was just a floor,water tank and stove still on it.After ripping that stuff off shortening it Im left with a tandem axle frame with wheels I can no longer get so to have a spare and the only thing I know about the axles is they have 10 inch electric brakes with drum hubs 4x4 bolt pattern and a 14 inch rim which limits the wheel I can use. What I think I want to do is change this to a more available sized bolt pattern rim like a chevy rim and at least a 15 inch tire but im not sure exactly what to do so I think I need to know what the axles are? Any help is appreciated sorry for the long rant!! Thanx
