I have a champion trike on an 05 RS Silverado thats not raked. The champion tree is over $1000. A social security budget won't cover that.
Found some that are cheeper but they don't accept the windshield or light bar and turn signals. What trees are you using? Can they be drilled to mount accessories or is it the rake angle that prevents their use? I already tried Bazooka but no answer yet.
