Marine deputies cannot back a boat trailer

I've been in trucking for almost 45 years, so I can back up quite well. I about got my head handed to me once when a guy at a boat ramp was having this kind of trouble and I kindly offered to help. Yikes, that set off the nuclear foaming-at-the-mouth profanity laced response! He never did get it in the water, after about 20 minutes of clogging up the ramp he gave up and went home.
Boat trailers can be troublesome. I usually use the Dakota to tow, but neither of my trailers are wide enough to show in the mirrors when exactly straight. I've DIY built vertical hull guides which stick out a bit more. If I was towing with the Dodge with the little camper they would be a PITA Even the GMC 1500, with no camper, is tall enough and wide enough that the damn things can "hide" back there. You sometimes must "intentionally wobble" to see where in the **** it is and is going LOLOL
