I upgraded boats a few years back. Got the new rig home and had that O Crap moment when the garage wouldn’t close because of the tongue. Never gave it a thought while looking at boats. It’s a Shorelander trailer, so I contacted Shorelander for a replacement tongue with the swing option built in. I didn’t want to deal with cutting the original tongue and bolting on a bracket. I figured this way if something went wrong with the swing option it was on Shorelander and not me. I had heard there can be issue with alignment. It’s worked out great though Shorelander would not sell me the new tongue directly. I had to have it shipped to a local dealer and picked it up there. The only issue was that the locking pin that they sent was undersized. It allowed a little play and at highway speeds the trailer seemed to sway back and forth slightly. I also noticed the hole getting worn a bit oblong which made the fit even looser. I went to Farm and Fleet and bought an implement pin with a larger diameter that fits snug and now things are fine.
Like someone mentioned above, I have almost no clearance. The motor is touching the back wall and the tongue gets rotated 180 degrees. When the door comes down there is less than 2 inches of clearance, but it all works.
Don’t you love it when a plan comes together.
Hope things work out so you can get the new rig.
