Bunks are simply carpet covered pressure treated 2x4s or 2x6s mounted
with some standard brackets. In your case I'll bet 2x4s will do with 4
brackets. My advise is to convert to bunks if the trailer frame is
basically ok. Your local boat supply store will have the brackets. An
enterprising individual could probably fabricate some from angle iron.
I use the cheap marine carpet from lowes. You only need a couple feet
off the roll.

I have a 12" aluminum jon boat. The boat's in decent shape. But the
trailer isn't. All of the roller brackets were rusted off.. lights not
functioning.. etc. The actual frame of the trailer isn't too bad,
though. I'm an inexperienced boater, and I'm not sure how to fix it. It
seems to me that the rollers would be kind of a pain to put on. And
someone in this group suggested a that rollers aren't even necessary
for such a small boat (especially aluminum). So I'm wondering, cand I
just slap on a couple of these slides and be done with it? Much like
this...

It looks like a very simple trailer setup to me. And it would make my
job of fixing the trailer up a lot easier. But is it practical? The jon
boat is a v-hull. Therefore, wouldn't it be better to put rollers on
for the boat to slide up, rather than the bottom hitting metal on metal
on the flat frame of the trailer? Seems like that would damage the
boat?
Let me know what you guys think. I'm anxious to get out on the water,
but can't until I get this trailer going.
PS The trailer has no bunks at this point, either.
