The Ram base is bigger and heavier than the Ford or Chevy.
I take the head off and then two person lift the base. I've done it by myself but that is asking for it...don't do that.
Now to do it by myself safely...I used a coupon and got a $100 engine hoist from Harbor freight. I still have to slide or walk it closer to the edge of the truck...then using one of these
Link... I can lift the whole hitch out.
Some leave the hitch attached to the trailer and use the trailer to lift the hitch and then drive out from under the hitch while attached to trailer....then reverse the process to hook back up.
