[Laredo Tugger]

When I had my TT I had the same problem. I would lift the latch lever and then try to raise the tongue off the ball and it would always get stuck. I carried a large hammer that I would retrieve and tap the top of the ball housing (with some lift tension) and it would always break free. Then kind of like the monkey who discovered a rock to clobber coconuts I realized that I already had a "hammer" in hand when I removed one of the torsion bars on the WDH. Just used it to tap the ball housing. Worked great.
