Anyone care to share some spare tire/hub carrier photos please?
Here is one I found for purchase. Spare Tire Carriers with Hubs
Most boat trailers today come with a spare tire mount, and small trailers just need a U bolt. I have had a spare for every trailer. Plus I always carry a tie down strap to tie up an axle on a tandem, or the many other uses tie downs have. I have carried spare bearings and a seal, but swapping races in the field requires more than a few tools. Swapping a hub requires one tool. You need a hammer to knock the bearing buddy off (Adjustable wrench), a tool to bend the cotter pin straight and push it out to be reused/or replaced (Adjustable wrench), and a wrench to loosen and tighten the axle nut (Adjustable wrench).

There is always a possibility the spare stub axle could be cut off the spare tire mount, and used to get you home. Welding businesses are not always that hard to find. Heck some Jeeps and other 4x4's are set up to weld. In our rock crawlin' crew we had three welders and enough spare parts to fix the common failures.
