We picked up our trailer today (Coachmen Viking 17BH). Everything went fine until we got to the storage lot. The coupler WILL NOT release from the hitch ball.
I tried all the tricks: moving forward & backward with the trailer chocked, spraying the heck out of it with WD40,jumping on the truck bumper. I cranked the jack until it was literally lifting my truck off the ground but that ball would not let go.
Dealership is 200 km away. I reached the saleman by phone but he was no use. Any suggestions? We'd planned to do a shakedown camping this weekend, but looks like I'll be driving back to the dealer instead. For this they charged me $199 for PDI?
