Gang, I have this crazy idea to add a non-functional Roadster style oil tank to a future project. It would be used to hold extra gear, tools or even function as an ice chest, so... I'm taking suggestions for something that looks similar, like perhaps a motorcycle saddle bag that might work. I've done a few web searches for Harley style bags, but can't seem to find anything I like. It would have to have a hinged and lockable cover. Any ideas on what might work, or on something that might be modified to work? The other side of the frame would either have a spare tire mount, or possibly a Gerry can bracket, like on a Jeep. Thanx, Gary.
