Hi...
I've just recently had a Class I hitch installed on my '96 SE. I haven't towed anything with it yet (no trailer), but was looking for the same sort of load range as you (I need to haul a go-kart rather than an ATV).
Anyway, the hitch is a Reese Shadow Mount 1, P/N 79072. It's rated for 2000lb MGTW and 200lb MTW (which is pretty close to if not over car's limits).
Hope this helps!
Cheers,
