My wife does just OK 75% but she trashed my tailgate and then denied jackknifing the trailer. Oddly she didn't do it on the boat ramp but when parking the damn thing in the lot.
My buddy's wife towed their horse trailers for years and nails the boat ramp about 99% of the time. With. a. stick. in his 94 12V.
I mostly gave up on her and asked my buddy to try. Nope, she doesn't get it - consistently. it's an attention to detail thing which she does poorly most times. Funny that she's a top notch nurse.
