i think some of those images above were using a single-axle trailer.
my WX1910 with a tandem-axle trailer:
– swing-tongue open and motor to the side = 258″ (21’6″)
– winch-post ladder step and motor to the side = 261″ (21’9″)
unfortunately, my garage is only 254″ (21’2″) wall-to-door so i needed to get 7″ of relief in order to fit it in. by angling slightly, i was able to do so. this took 127″ (10’7″) left-to-right. thankfully, i’ve got 147″ from centerline to the side wall, so i could do this with room to spare around the side and still allow space for my wife’s car to park next to it.
