Regarding the backer bolts or stop nuts as Randy Bishop noted in an earlier post.
There is a set of bolts that hold the threaded rod to the trailer and are tight to the outside of the trailer.
Then the stop nuts, which are spaced between the trailer and the spare tire.
Then nuts to hold the rim to the threaded rods.
Hopefully that makes sense. The stop nuts keep the tire AWAY from the trailer enough that the bolts don't pull through like they did on our trailer.
Using my previous pic as an example:
Hopefully this helps.

I can't really tell from the photo's how bad it is but you might be able to put them on now and it be OK..Also a spare rack mounted on the bumper as you mention would work..As far as trying to repair the damage I would probably try to seal the cracks and leave it along, because anything else would require a paint
job to cover the repairs.......Theres a product that some people on here has used called Captain
Tolleys Creeping Crack Repair.... I personally have not used it but maybe someone else can chime in that has used it and tell how it may have worked for them.....It should help on any stress cracks you may have also..If after a good scrubbing there's still a faded look to it you might try sanding it down with 400 grit sandpaper.One of my trilliums was faded pretty bad and that worked great for me I used a electric palm sander and went over the entire camper turned out great, just make sure the gelcoat doesn't have any thin places in it where you might sand down through it and expose the fiberglass underneath..The gelcoat on most of these is fairly thick enough to take a little sanding just be careful..How big are those tail lights
, I've got a set of round LED's I bought once to put on a Burro
I once owned but they didn't work out.. If I can find them and if they will fit they are yours since your doing this as a favor for the folks...I'll dig around tomorrow and see if I can locate them and see what size they are.... The best that I can remember they were around 5" or 6" but can't remember for sure....GOOD LUCK WITH THE CAMPER RANDY...
