The 4 d rings came with it. Was radial tires instead of belted, different wheels, a second roof vent and a few other things that made me roll my eyes at the guy. Trailer didn't even have an rv style door, it had a pipe latch type of thing. Was not very thrilled by it. Guy I spoke with reminded me very much of a used car salesman. When I was there somebody was picking up a open car trailer. Overheard him agreeing to buying a spare tire...for $240. I just got off the phone with the place in Georgia....a spare is only $120 from them. I will be spending some time online looking around. I was hoping that I could get my first set of injections next week and then make the trip in late September but that ain't gonna happen.
