2 orange cones placed at each side and how far back into a space where you want to back the trailer into.
2 magnetic balls placed one on the hitch and one on the receiver. After a few times out you will be able to hitch up without them. Found at any parts store or RV camping store.

That's ALL you need to RV solo with any RV!
No screaming, yelling, waving of hands, walkie talkies etc...... just 2 quiet cones telling you were you need to be while you are backing up AND you can 'throw them in the RV bay' when you are done, can't do that with the DW.
Good Luck, Happy Solo RV'ing you will love it. :C
