Brand new 40"x48" HF trailer, still sans decking and never been down the road. It's actually parts from two incomplete kits I picked up from a surplus store, between the two there was enough for one trailer so that's what I did. It's the 8" tire one, but you can always add the bigger tires later if you so desire.
Comes with a spare tire, as well as spare hub and bearing assembly, and your choice of round or square taillights. Does not come with MSO or title, since SC doesn't plate small trailers, so you'll have to register it as home-made when you get it home.
$100 as-is, and for $25 more I'll add a 3/4" plywood deck or for $40 more I'll deck it in either 5/4" pressure treated decking or a 1/8" aluminum road sign.
Buy the trailer and the Miata parts or tire balancer and I'll do the plywood decking for free and have it loaded-up and ready to go when you get here.
Edit: Sold, thanks guys.
