Looks like it is galvanized which is a plus. Axle has lost cap, replace with bearing buddies, also replace bearings and seals. Replace broken light. Check tires for cracks, if cracked replace. Check axle to see if bent. Get a spare tire. Can you do the repair work? If axle and tires are OK you can probably get by for less than $100.00, excluding spare, if you do most of the work.
