What did you end up getting to assist your loading and unloading?
I am going down the same path - I want to get a TC to haul a B3, Leslie, etc, figure it will all fit, but I need a ramp or lift to help with the loading. I was looking at the same ramp options you were but not sure if it would fit... Didd you get a ramp or lift gate? Which one fits in the TC and works well with a B3, Leslie, and pedals?
