I got this old 12’ ModV boat and trailer free from my in-laws. It’s a custom trailer and the tongue is ridculously short (1 foot). It’s unforgiving to back and I dang near have to put Mama Bear’s Acadia half in the water to launch. Also, it has an old coupler where you have to tighten up on the ball with a large hand nut assembly. One time at the ramp it actually came off the hitch! It made a loud clunk sound. I thought buggered up her ride. I was thinking, “She’s gonna $@#t! She’s gonna kill me!” Luckily the chains caught it and there was no damage. But you should of seen me trying to pull those two back together on the ramp like He-Man. No wonder my back is screwed up. What is nice about it is that it can fit sideways in the garage nicely, and the boat and trailer only weigh about 300lbs. When I look at my buddies Nitro trailer he’s got a “swing tongue.” I figured I’d buy one. Kind of expensive. Then I was thinking why don’t I sleeve it. I’ll grind off the old coupler leaving the foot long tongue (doesn’t sound right). Then I’ll slide a 3-3 1/2 foot peice with a modern coupler over it. I can pin it or use grade 8 bolts and take it off in the garage. It makes me wonder at what point do I just get another trailer? What do you guys think?
