I wasn't saying to unhook the trailer, just jack up a ways without lifting the back wheels of the truck off the ground. I can gain 4-6" of front height that way and loose that sharp ramp angle!Yes but I don't like doing that. Turns the whole trailer loose - no parking brakes on it. I just watch where I park as much as I can and try to make sure the ground at the end of the drop down is high enough to clear the hinge point. Back wheels of the truck higher than the trailer wheels helps too.
