I park my 30WLA (36') next to my garage and it's a tight squeeze, but it fits pretty easily. It's hard to explain, but I go in at an angle and then tuck it right in next to the garage. My street is narrow, so that limits the entry angle. One warning, if you park right next to the house/garage, watch the corners of the building. I almost tagged mine but noticed it before impact. The trailer is much wider and taller further out from center than my 24' boat was. When I'm backing in, I unhook the WD chains/bars and I could get it to 90 degrees, but it isn't needed.
