Why not just lay it on the tongue of the trailer with a long bolt down through one of the lug holes?? I built my trailer myself, it's a tri axle with 8x6.5 lug pattern. Same as my truck. I just waited until my truck needed the front wheel bearings replaced and welded the old one up in the trailer tongue. Spare tire rides up there down inside the 12" I beam neck. Out of the way.
