I'm about to have to replace my existing load equalizing hitch (chain linked type - unknown brand). Is there a consensus for a preferred brand/type for towing the smaller AS's? I have a 21' that I pull with a Ford F-250 short bed crew cab super duty diesel. I've never had any sway issues with this trailer and can run w/o load leveling although not quite ideally. I have an old "inherited" hitch available that I think will work with my existing receiver drop bar, if there's no strong reason for buying something like an Equal-i-zer hitch. Recommendations would be appreciated.
