What one would you use?

I'm looking at the new hitch because sometimes in the mountains my hitch binds us due to the fact were on uneven ground. We very rarely use camp grounds, would also like the option of loading from the side.

Thanks for the help so far will be doing more research this weekend.

I'm towing with a '12 Dodge ram 3500 8'bed 4x4 CTD 6sp manual.

I tried to put this in my signature but being computer stupid I failed to do so.
