Could you guys stop arguing about stuff for more than 5 minutes to help someone out?
And, trying to thread the needle with a stinger locked into a trailer hitch into the truck’s receiver is an act of futility at best and an incident at worst.
OP, just ask someone, anyone, to lift the hitch and get it in your truck’s receiver.
WD bars, depends what you have but using the trailer jack and/or a cheater pipe may be necessary.
If I was closer I’d come help ya. Good news is there’s no lack of RVers in FL. Help can’t be too far away I’d think.
